Your username: Zombeh In which minigame/server does the bug occur: Creative1 Detailed description of bug: The birch floor seems to have been replaced by magenta wool in this specific area. I think it was because the 2nd data value of wood was birch and the 2nd data value of wool is magenta so it was most probably a typo from wood to wool. Coords provided in screenshot:
ItsHarry said that it was a bug when generating the Creative World. Staff don't fix those anymore cause there is tons of magenta-glitched roads in the Creative world.
As others have said, this was caused by a very old bug in the generator. Unfortunately, any chunks generated during that time are affected, it was fixed a long time ago.
