Heya, I got crash when updating to newest GT (6.11.03) from 6.10.25 as we update every few weeks when we have time to play..
Gany's Surface has config to disable/enable bunch of stuff, we had basalt disabled since the start of server few years ago. Enabling it fixed the crash, but I believe you might want to check the detection stuff on your side. Assuming that mod has enabled all freely configurable stuff is probably not really wise and this looks like being introduced just recently from new GT
Have a nice day
Well uhh, I would keep its Basalt enabled, it generates using the GT6 way of Worldgen too.
