Crashing on a Forge server (in a custom modpack)

Hello, I have an issue with this mod, crash log is https://pastebin.com/MmdiJGBb.

In short, I've investigated the issue, and, based on the string from the log, the part which causes error is this: NBTTagCompound compound = entity.serializeNBT();.
I have some mods which modify mobs, also because this is a server there are other players, so I think that your mod doesn't have a "limiter" and it basically tries to serialize NBT and get spawn egg from every entity.
Also, when looking on the circumstances of the crash, it happened when I've got killed by a Spider. So, I can say that error is caused because mod tries to get NBT and spawn eggs from players, and it shouldn't do this (get those from mobs only).
Thanks a lot if you will investigate this issue and help me (and probably others too) out with it!

Hi, thanks for the heads up but sadly I have very limited time and will not be able to resolve this issue at the moment. Sorry

No problems, I don't want to force you to do anything, so I'm completely fine with your decision :)

Note: I'll try to change the configurable spawn rate to 0.0 (instead of 4.0) and see if the error happens again.
