Thanks for responding i really appreciate your time in looking into this
i have narrowed it down to the items.json
in previous versions i was able to edit this .json to allow various handguards, rails etc to be put on guns etc that would not otherwise be allowed to for example allow 2 orsis rails and a skeleton foregrip to be put on the ak handguards to make the character look like they are holding the gun by the mag.
i made literally hundreds of changes in my older 2.2.1 version
however in this version i can make the edits ( only 2 or 3 so far over 2 days) and the game runs fine (for example tonight i made an edit played for just over an our with no issues) then after a few raids i get the error. i re-installed a fresh version of 3.5.0 in a separate folder and transferred the new items.json in to and it ran totally fine.
so there seems to be something in this new version that when it tries to load the bots in raid it has trouble looking into the items.json if any edits are made.
i can send you the items.json that has the edits in it if you like
