When I use the latest version of Ex Nihilo Omnia, slowly my world becomes laggier and laggier. Testing it in a world, at first when you break a block, the drop appears immediately, then after waiting a little while, if you mine a block, the drop appears a second later after you finished mining it. After a while, it will not ever let me mine a block, it just ends up reappearing as if it was never broken to begin with.

I tested this to make sure it wasn't an interaction between it and another mod, it seems to solely be Ex Nihilo's fault. I am not sure what seems to be causing this issue. Downgrading to Ver. 1.1.3 seems to fix the problem.

I'm trying to fix this, it has something to do with moss growth, so if you disable that in the config it should fix it for now.

Cool, thank you for the response! I didn't want to have to take this mod out of my Skyblock map.

I see allow moss spreading in the barrel options and can moss spread at all in world manipulation. Do you need to disable both of these options?

If I'm not mistaken you're calling the spread moss code every tick which causes a lot of excess garbage for the GC to have to take care of. I recommend you add a random chance variable for spreading the moss here.
