Hi,
We've encountered an issue yesterday with M28. The two M28 AIs would not do anything upon game start. Here is the relevant replay in case it could help: https://replay.faforever.com/20630807
Do note the same map with M27 instead of M28 was OK (everything else was identical).
Another issue we had, that might not be related to M28/M27 at all: all 3 games we ran yesterday (2 with M28, 1 with M27) were laggy with frequent micro-freezes (no apparent connectivity issues between players, same PCs as usual and same group of players as we usually do). Again, this might not be related to your AIs at all, but I thought this was worth mentioning.
Thanks again for your hard work, it is very much appreciated.
