Latest version of TR and Forge 2088, the json config files for oregen dont seem to have any sanity checking currently,

What this resulted in was an inverted max/min value causing the game/server to crash on load with an index out of bounds error. Obviously a config error on my part but a little foolproofing may be useful in the future.

Ah yeah, that should be easy to add.

Ive added a few checks, I could go on for ever adding them.
