Wow. Just... wow. That save is about 9500x as intense as any of my saves so far LOL, looks super fun though.
I got it working. The problem was with the higher tier bob's turrets having more than one inventory slot, and how my code handled the situation. Will probably end up helping compatibility for a lot of other mods as well so thanks for your help.
I want to point out though that if you plan on having tons of turrets for chests to load, (which it seems like you will LOL), I'd play around with the config values a little bit. I balanced it for early game vanilla so right now it's hard capped at 5 mags per second (regardless of how many chests you have). Increasing max_ammo_per_cycle and max_ammo_per_turret would go a long way with very minimal performance loss. If that's not enough, lowering ticks_between_cycles or raising max_chests_per_cycle should do the trick at a higher performance cost.
Also, the chests are fully capable of inserting any of bob's ammo types, but will do so in a random order for each chest. They will, however, attempt to use only 1 ammo type per 1 slot (so for instance, the mk5 turrets can and will be loaded with 3 different types of ammo).
Just a heads up. :D
