My ideas for some bugs.

Sorry if someone have posted this. I have and idea for the bug that if you upgrade a unit while building it, it could not be finished. Why don't you set the upgrade make new unit available and set old unit pop cap to "0" so that it can't go out but we can undo to get back resource. Don't need to remove old unit build icon, it will automatically be unavailable if its pop cap is 0. Just write this description for the upgrade "T34/76 is no longer available, only the new T34/85 is now being produced".
Also, I think that red banner strelky is a bit lazy, they don't jump into combat although they have SMG, I saw all of my RBS squads just standing to watch their comrades fight and die. I guess that problem come from the "red banner pistol". The range of that banner may be too long so that the squad don't come in. Maybe 2 version of red banner, one short range (equal to SMG's) for SMG squad, one long range (equal to LMG's) for LMG squad. It won't be too hard to code.
Thanks for the great mod. And sorry if this post annoy you. I just want to help.

No don't worry, this post may be useful. Thanks for the educated pointers, we will look into them.

I had some matches with my best friend today. We played Wehr, along side with a Normal Wehr, facing 3 Normal Soviet. We had hard time holding off overwhelming Soviet forces, but after some minutes there was no any Soviet offensives. I guess that as the AI trying to upgrade its units, it reached a goddamn bug that stopped them from buying more units. And as it is AI, it don't know how to destroy that building and build a new one. So you can see, that bug really affects gameplay as many player like us still want to play with AI "Got no mates? Play against AI."
And he also tell me that EF crash on his new laptop although it ran smoothly. But on his crappy desktop, where EF lagged like hell, no crash happened. Also need to say, he don't know much about computer, so I can't ask him to give me more detail to report to you. I have 2 computer, 1 desktop and 1 laptop, both run EF smoothly and stably.
I really want to see your actions against those flaws soon, as I noticed that lot of people start to lose temper. After seeing the Soviet's spamming and the following standing by, my friend suggested me to play vanilla CoH or another game.
And one more thing to say, the Soviet is still imbalance, as it can overrun German infantry, its soldiers are weak, but they come in number. German soldiers are stronger but imagine, 3 guns against some 10 guns? Also, the new AI is so effective for Wehr, AI PE build BergeTiger but don't know how to use it, AI US and Brit seem to not improve much, and Soviet AI facing bugs and they keep charging Katyusha to enemy bases (maybe trying to code them behave as Neberwefer?).
I really don't want to complain, and I didn't complain. If you think those lines are complaints, I'm really sorry. I just want to see the mod better and alive for a long time. Thanks for spending almost 3 years creating this great mod.

I agree. It'd be nice if the T-34/76 button would be disabled or something while the T-34/85 is being researched. And maybe make the upgrade time a wee-bit faster?

Why not just make the upgrade time instant and have the build button disabled? It'd be the same thing other factions get since they're able to upgrade mid-build.

You'll still have to wait for newly constructed vehicles to pop out upgraded to be able to use the new abilities, so there is still a semi-upgrade time.

When will 1.05 patch come out? My friends and I decided to not playing Soviet (still play EF because of good AI) until the bugs with upgrades are fully fixed. We don't like to play Soviet already (not our favorite playstyle), but we like killing them with elite Germans. The bug ruins gameplay devastatingly. Imagine after holding your ground for 30 minutes, suddenly the battlefield becomes quiet. The only thing you face is some Partisan squads, or some Kayusha trying to charge your base (if AI chose Breakthrough, maybe some Tank Raiders).

And one off-topic question: AI have resources mutiplier, how much for each level of difficulty?
