I'm running a 1.7.10 Forge/Spigot (Thermos) server that had Realistic Terrain Generation (RTG) installed. After one of the map resets we've ceased to use RTG's world type and soon (though after the world has first generated) completely removed RTG from the server. However, the "Skipping Structure with id rtg_MapGenScatteredFeatureRTG" message started spamming the console every time someone generated a new chunk, which very soon became annoying.
Although I know that this issue has been addressed several times it has never received a proper answer. In most cases people got told to reset the map, but this sure isn't the only way to fix this issue. To my best understanding, the problem lies somewhere in the NBT files, where a list of enabled structures seems to be kept. The proper way to get rid of the spam would be to delete the mention of this structure from all appropriate files. I've checked all files that I thought could be relevant to this issue (such as level.dat) but found nothing. Obviously, if Forge still "remembers" RTG, it must be mentioned somewhere, right? Where should I look?
Thank you in advance,
