hey i am having a similar issue, it might be some incompatibility with another mod but idk. but when ever i try to pick up the long handed inserters and just the long handed ones, it wont go into my inventory, not like drop onto the ground because my inv is full, it just disappears and my only solution is to craft another. i have made it through 1 game with this problem trying to ignore it but starting a new one caused my to craft somewhere between 50-200 long handed inserters, i placed them all in the order needed and then promptly realized i placed all of them wrong. now i need to pick them all up, and then craft them all over again because they fuckin disappeared. would be awesome if you could respond and help me i can past my mod list down here:
Air filtering, auto deconstruct, auto research, base mod, belt layer, bob's assembling machines mod, bob's functions library mod, bob's greenhouse mod, bob's mining mod, bob's power mod, bob's technology mod, bottleneck, bullet trails, chunky power poles, configurable underground lenghts, construction drones, even distribution, inserters dont need power (i think it might be this one but it has worked with this mod before so idk), power armor mk3, quality of life research, RitnLIB, robot mining site, side inserters (also might be this one), uranium geiger, waterfill, Where is MyBody,
thank you for your time i am a modder for other games myself and i know how hard some things can be, so no rush, thanks!
edit: disabling side inserters did not fix it but i am now noticing that when i pick the long handed inserters up it gives me a regular one instead,
edit2: looking at the mod settings confirms that i am, indeed, a dumbass.
