Did you try to reproduce it without FoamFix?

I will do that right now. Sorry been busy the dev told me to report it.

@asiekierka I can confirm foam fix was most definitely the cause. At any rate I am not a coder just a testing dummy ;) so you will have to contact @ternsip to figure out why its having problems.

I can't imagine what cause such issue. My mod doens't affects minecraft native classes.

@ternsip Oh, if I could imagine what causes this, I'd probably have it fixed by now.

@asiekierka if it helps your information ... I tried 6.1 anarchy and lawful and both produced the same issue. I will start testing old versions of foamfix when I have the time. I noticed in life I seem to eerily good at finding obscure bugs.

Can you please make a legacy dump so I can?

@ternsip for the record using your schematic packs with recurrent complex foamfix has no problems. You may want to ask @Ivorforce for assistance in squashing this bug. He has a great wealth of knowledge in understanding the minecraft chunk and spawn algorithm and has re-wrote his mode twice to compensate.

@P3rf3ctXZer0 Lawful is not likely to cause this - it doesn't edit Minecraft base code in any part related to worlds or block states.

This issue does not exist in 1.11.2 - Not sure if the will help. I am starting to test things a bunch. Also it did ... sorry if that confuses you but lawful also had the 1.10.2 crash ... I have no idea why ... At any rate I have jumped to 1.11.2 to see if the issues persist ... I may be forced to leave 1.10.2

Allegedly fixed.
