Lamp changed color in singleplayer while AFK and paused [Minecraft 1.20.1, Fabric 0.15.11, PF 1.2.1]

Bug Description

[Edited, formatting was broken]

I am baffled. I would think someone pranked me if I weren't home alone and paused in singleplayer. My lamp was pink when I left to use the restroom, and when I came back to sit down, it had cyan stripes. I feel like I'm going crazy.

My resource packs don't modify any of this, at least as far as I'm aware. My resource packs don't create multicolored wool, so even if PF pulls from my resource packs, this doesn't make sense.

Breaking and re-placing the lamp does not fix it, but it appears flat pink in my inventory and in my hand.

Closing and re-opening the world does not fix it.

Closing and re-loading the entire game does not fix it.

I went to a different structure I built that already had red lamps, but they weren't affected.

As an experiment, I decided to check and confirm that pink wool is not recolored from my resource packs. It doesn't even remotely look like the lamp.

I also made a different pink lamp to see if it affects all pink lamps, or just the one in that room. All pink lamps appear to be affected.

I have absolutely no idea how this could have happened and I'm half tempted to run a virus check to see if somebody hacked me just to pull a prank.

Reproduction Steps

1. Pause game in singleplayer
2. Walk away for 5 minutes to use restroom
3. Come back and unpause game

Log File

The log was too long for me to submit, so here's the chunk that was output when I did the last test, to see if all pink lamps were affected.

I went and played as normal for a little while.
When I went to lay in the bed, I had to do a double take because the lamp was back to normal.

I'm losing it.

Update:
It just happened again.
