Currently the one thing I am aware of is AI being unable to use PCHBA "swing" properly, this is due to how the source code of the game is coded, sadly not much I can do right now.

i made a dupe with your stuff but i might be a vanilla bug because i went on a shuttle and completed a mission with the shuttle but when i went back to a save i still had the previous items. may also be a bug with another mod i had. seems alright so far tho, loving the mod and weapons :)

That's strange, can you explain to me as to what happened step by step?
Do you mean you went back to a previous save with new items you didn't have in the previous save?
If so then it's a characterdata bug that would affect everything.

so i finished a mission with a shuttle that couldnt dock because it had a docking port not hatch, and this caused me to be softlocked so when i went to a previous save, i had the pcgl 26a3 and the exosuit but duped it as i had another one on the main submarine. basically i duped by going back a save where i had the exosuit equipped on the softlocked outpost, but when i went to a precious save i had the exosuit equipped still and noticed i had my previous one sitting in my control room.

Must be a new baro bug. I don't mess with saving of variables.
