Well i did brought the texture limit / black screen topic, wich have been also mentioned by Stark and Chemz and others. Black screens midgame aren’t properly adressed yet (aka we can’t know if it happen due to a new building adding a ground texture and thus breaking the game, or if is a totally different issue). It could be an engine limitation, but afaik it wasn’t there on vanilla.
Chemz made a post that aggregate most of the issues:
What the actual hell did you guys do to Scenarios?!
So the feedback is there.
Then you have the bugs that carried over from vanilla. I admit i had a vague hope ModifyProtoUnit would be fixed, was hyped for it. XD
