From what i can observe, my server seems to crash when i remove block or place blocks obtained from the "Too many items mod". but I am still not sure if this is the exact problem.

The mods work perfectly in singleplayer without any errors.

I am using this server: forge-1.7.2-10.12.2.1121-universal

 

These are the mods I have on the mods folder:

[1.7.2]ExtendedWorkbench v1.2.0.3

AnimationAPI-1.7.2-1.2.1

BattleTowers-1.7.2

CustomMobSpawner 3.2.0

DrZharks MoCreatures Mod v6.2.1

Elemental Creepers-universal_1.7.2-4.1.1

MutantCreatures-1.7.2-1.4.5

TooManyItems2014_01_13_1.7.2_Forge

twilightforest-1.7.2-2.2.3

 

this is the error log:
