little tiles mod doesnt works

little tiles mod and creative core makes my server to crash and i dont want to remove them what do i do?

i realy want this mod to stay but at the other side my server keeps crashing

Forge server log [#YACsUiK] - mclo.gs

i tried that with magma too but it didnt work either

and about removing it it works like that buti would like to work with this mod

is there another way to fix this i had the same problem with chiseled me its a cool mod but it doesnt work on server but in normal minecraft it do

thank you about it i removed the smaller units and it worked thanks
