"Async chunk load took way too long" [Bug] [SP]

[lAimBotl]

I get a "Async chunk load took way too long, this needs to be reported to the appropriate mod."
When trying to load a world, removing the mod lets me join the world,

Last thing I did was place a primitive alloy smelter down,
but I tried to recreate it in another world and nothing happened.

I did see "at com.enderio.machines.common.block.MachineBlock.getLightEmission"
and "at ca.spottedleaf.starlight.common.light.BlockStarLightEngine.calculateLightValue"

Here is the log (no crash, the world freezes until I close it with the task manager)

I seem to be having a similar issue with it, saying something about async took too long and something starlight chunk loading as well. also stops when I remove starlight.
I didn't get a crash either
