Assuming this is a bug because it was possible before the update to the server -- signs with color codes in use will not assume those colors in its text.
If possible this could be allowed for donators if not all players
This is hard to replicate but bear with me - multiple people have experienced this
When in the nether or end, you will occasionally be teleported to the "overworld" against your will
However despite the fact that the sky appears as if it's the overworld, your coordinates have not changed, no blocks will display, and all models and mobs will still interract with you (including trying to kill you)
To replicate - just hang out in any other dimension while fixing bugs for 20 mins and you will see this happen
The world will flash for a moment and appear to disappear; the player's cursor will go to their first hotbar slot; and the armor bar will hide itself
Lela connected this to chunks being added to a player in the Discord chat but I cannot verify that
To replicate -- walk around for a while
May be the Overworld counterpart of the other glitch "Dimensional Teleportation" with details in that thread
Not a single ocelot has spawned naturally on this server after hours of multiple people searching a jungle, and the forums do not cite ocelots as being a rare spawn / they should occur occasionally in the jungle above sea level.
