[BLOCKING] Phantom Redstone

Publish_478003

Summary:
I apologize for the vagueness of this bug, but we are having trouble causing it to happen. It seems to happen randomly. Either upon a world reset, or randomly during the middle of a playthrough, we will have redstone components that seem to forget what they are supposed to do. Repeaters will be unpowered despite having power, redstone torches will be receiving power into their block and stay turned on, comparators giving false outputs, buttons will refuse to power the block they are attached to, etc. Breaking the component and replacing it returns it to normal, but it doesn't update the other redstone components around it, so you end up having to replace every impacted component one by one by hand. We ran four simultaneous tests of a map and had it happen on one of them but not the others, then ran another four tests on the same version and had a different person have the same issue in a different spot. We think it may occur more frequently while Plutonium Mode is active, but we can't prove it.

Impact:
This bug is potentially blocking any content that uses redstone from working consistently. It is hard to repeat, but when it happens it completely disables the map and the map needs to be reloaded from scratch from the beginning for another playthrough.

Repro Steps:
1. We do not know how to reproduce this bug. I will attempt to get the save files of each instance where it happens from now on.

Observed results:
Redstone components stop functioning.

Expected results:
Redstone components should not stop functioning.
