-Fixed 1939 AI not upgrading its infantry templates, making them much weaker compared to 1936 start

Please explain. Sounds like very bad bug.

- will research heavy tanks, and tanks in general more

Does this mean the USSR AI doesn't research Heavy Tank on default?

Recruitment explained in the comments, both the other ones are too low priorities for AI, it's complicated issue, but in short In 1939 Germany takes a very long time before switching infantry (the most used unit) to a non-default template. Just 9 inf without much support companies cannot push through anything (and GER is the agressor ...) .

Soviet heavy tanks - vanilla ai has extremly low chance of picking a heavy tank research. A niche fix since they only use heavy tanks in 1939 start where they start with some templates containing heavy tanks. But seeing them still produce and use a T-35 in 1945 was silly.

Hey KubiG just wanted to make you aware of these two new mods.

https://psteamcommunity.yuanyoumao.com/sharedfiles/filedetails/?id=2506845603 This mod attempts to fix the huge issue of the AI being hardcoded to delete all ships below 25% complete on game start. Only problem is that they will only assign 1 Dockyard to the re-added capital ships. So it also gives the AI a big boost to Dockyard output. I think it may be possible to get the AI to assign more than 1 Dockyard if new templates for the re-added ships are added to their AI brain?

https://psteamcommunity.yuanyoumao.com/sharedfiles/filedetails/?id=2686889063 This mod attempts to fix the huge issue of the AI building goofy all Screen ship fleets.

I missed the question: Yes you can add as many templates to the AI brain :-) But you must also convince the AI to 'want' that ship class (e.g. it must feel it needs more battleships). It's tricky because it's all done in 'ratios', not number of ships. Which is really bad at times because if for example AI looses all screens, it will suddenly have too high BB ratio and cancel (or deprioritize) all BBs and instead start building screens...

Found this bugfix mod the other day. Thought you might be interested in it.
