For those who are crashing because of the Milkor grenade launcher

I’d been troubleshooting a specific issue where the game freezes into a white screen after 20 to 30 minutes into random raids, after reviewing the crash logs from two different incidents, this error popped up in both logs:

Item deserialization error: item patron_40x46_m406 (id: 68bb0fc54c53578cc4025fc5) has too large stack count 1 when StackSlot cartridges in item mag_msgl_milkor_cylinder_mag_std_40x46_6 (id: 68bb0fc54c53578cc4025fc4) only allows 0

Essentially, the game is trying to load a grenade shell into the grenade launcher’s cylinder, but the cylinder’s capacity is, most likely due to a conflicting mod, being incorrectly set to zero. The crash probably happens when a bot attempts to load the Milkor, or the map tries to generate a Milkor with shells in it.

So obviously, I, with zero coding experience and had promptly given up on the search of hours on the SPT workshop for a solution, turned to ChatGPT. I gave it the error logs and my mod list, and it generated a mod that seems to have solved the problem for me. It’s a tiny little server mod that forces all 40×46 magazines to have a non-zero capacity (6 for cylinders like Milkor, 1 for single-shot launchers). It runs after most of the other mods load in and fixes whatever another mod broke.

I haven’t experienced the same crash since putting it in the list, at least for a few raids in a row.

All files were generated by ChatGPT, I quite literally wrote nothing. I just wanted to share this quick fix in case anyone else experiences the same issue.
