Ticking entity crash when installed with Alex's mobs

[Marshall-Mellow]

Going in a mineshaft with alex mobs and spawn structures installed causes the undead miner to crash the game. idk how or why considering this mod only adds like 1 structure to the world. My survival world was bricked and removing this mod solved the issue. Here's the log of the crash

Hi there! I am so sorry for the late reply, been super busy! Unfortunately, I have run into this issue myself, and I am just as confused as you are. Have you tested this with only Spawn Structures and Alex Mobs installed, and/or removed Spawn Structures from your modpack to see whether or not the issue persists without this mod installed? I will continue looking into the issue myself, but so far I have drawn a blank as to why this particular mob is clashing with my mod.

I completely forgot I opened this issue lol. I did try it with just those 2 mods but couldn't recreate this issue, I do remember that the world I had that crash on worked fine after I removed the spawn structures mod. The only thing I can think of is a third mod (or maybe even another one) in my modpack causing this problem when present along with alex mobs and spawn structures. I will try and see if I can figure it out but it would be very tedious to do so and I'm not sure I have that kind of time. I would have to make new worlds and go to mineshafts and see if it crashes, until I narrow it down to a the mod conflicting with the 2 mods present, that is, if that's even the case.

The same problem, it happens because this mob checks the nearest structures, and the mod "Spawn Structures" for some reason breaks everything related to searching for structures, for example the /locate command. This error occurs when 2+ launching a world with a mod.
