@humanpotatoe @FunkOff @ZLO Thanks. I analyzed the reasons, which may be caused by the recent use of this mod: Preservation Project Demo by PreservadorX3 Antares_Unit_Pack.rar https://www.moddb.com/mods/antares-unit-pack-300/downloads/preservation-project I personally think this mod is very interestingļ¼Œbut because it is a trial version, some scripts may conflict with the mod of this forum. It's much better after the suspension. Thank you again!
