Custom dimension with custom biomes causes crash on load
Sat, 09/05/2020 - 05:43

Hey, all!

I'm here to report a bug and/or hopefully get a little bit of help with it. I'm trying to make a dimension with some custom biomes, but when I attempt to load in it crashes. Part of the issue is that what causes it to crash is a complete mystery to me - if I only set the dimension to use two of my custom biomes then it's fine, and sometimes I can even get it to use up to four, but after a few attempts to start a world and generate the dimension it will eventually crash a few seconds after I enter, presumably while it's trying to load the chunks around where the portal spawned. The weird thing is that once this happens, that's pretty much the ball game for those biomes in that dimension, because no matter how I change it afterwards (using fewer biomes, changing the generation settings, using entirely different biomes, etc.) the dimension will permanently be broken so long as I use whatever biomes I had in there when it crashed in the dimension. If I make brand new biomes it'll work fine, until of course I make some changes. The last time it happened (the crash the upcoming crash report is from) I didn't even change the dimension's biomes - I did make new biomes, but I forgot to add them, and even though on the last test it loaded just fine and I could explore as much as I wanted with only two biomes, when I loaded it up the next time it crashed upon spawning.

Does anyone have any clue as to what this could be caused by? I've made another dimension using vanilla biomes and it seems to work just fine, so I suspect that custom biomes seem to be part of the problem. Here's the crash report:

In one of min/max settings, your minimum is set to larger than maximum

Oh! Alright, well that's a good start, thank you. Any idea what setting it could be? I'm not having much luck in finding any settings relating to biomes or dimensions that have a minimum or a maximum. I thought for a moment it might be biome height, but then I realized that's just base height and height variation, not a min/max range.

A quick update! I boosted the biome spawn rate really high and set it to spawn in the overworld so I could test it there, and I get the same result: it just crashes the game once I try to load more than a few chunks of the biome. This isn't even the same biome that caused the crash the first time as I've tried deleting the original and re-making it slightly differently several times in hopes of it working, but it's made in a similar way, so I guess the cause of the crash is still there. Here's the crash report for it crashing in the overworld if that helps:
