Hi, I'm just writing here to let you know I updated to your latest version from the last one and I'm now having performance issues. My FPS/UPS, on single player, is usually a solid 60, 59 sometimes, but with your new version for some reason the fps/ups drops to 53 then spikes back to 60, then back down causing what feels like lag. I don't know what's causing it, but, disabling it fixed the issue. Just thought I'd let you know.

Nevermind, it seems toggling the mod and reloading fixed it. Sorry!

Thank you for letting me know. The latest update changed from storing everything in a list to storing it in a table. This was done for two reasons:
1) removing an element at a given index of a list is slow, which might cause a lag spike on large bases
2) finding an element to be removed in a list is slow, so lights from entities that had been mined/destroyed was allowed to survive until the next time they were to be updated.
The change has caused slightly higher CPU load in general (est. +5%), but hopefully with fewer spikes. I had a hard time benchmarking this, so any observations are helpful here.

I have removed the 0.5.0 update until further notice, since it appears to have a weird bug, with some signals not updating.
