When I leave a chunk with an Ether block(s) in it and let it unload, then reload the chunk, the particles of such Ether blocks disappear. This also happens when I exit and reload the world, despite being in the same chunk. However, this does not occur with dyed Ether blocks.

I am playing with many mods, so I'm unsure if a mod(s) is be conflicting with Malum. Though, it's quite odd that this doesn't occur with dyed Ether blocks, so I doubt a mod could be causing it. Just in case, though, here is my list of mods:

Mods that are also included but not present in the list of mods include: Spice of Life: Carrot Edition 1.12.0; Apple Skin 2.4.0; Twilight Forest 4.1.1052

EDIT: The one non-dyed Iridescent Ether did not have particles; it was also affected. I just replaced the block before taking the screenshot.

This was an issue in the base version of malum, I fixed it with a rlly temporary solution.
I'll keep this issue open in case anyone wants to help with the following

i think that optimization is silly and hurts more than it helps

Fixed in 1.4
