For some reason, this mod couldn't work with Grenade yeet, not like it's incompatible with that mod, it's just that the gimmicks of the mod don't work with diagonal inserters.

I looked into it and the Grenade Yeet mod is making an assumption that all inserters are straight.
It uses the direction of the inserter base platform, instead of calculating the angle from the drop position.
Unfortunately, I can't do anything about it on my end. It still technically works, just not in the direction you would expect.
