Just discovered a new form of jumping involving detballs; head to the NAB Community Facebook page for more details

I hear linux is picky about capitalization, make sure that they're correctly capitalized in the list.

Thanks, it doesn't happen on my Windows machine, only on Linux (wine)... perhaps those maps require more graphics memory than wine is allocating?

I'll have to look into this

PM-Cypher doesn't either :(

Hmm, so far it doesn't load: Probe, Barracuda, PMX-Lunar and Wolf'sBayRemix at all, instant crash with the same error. the in-game "maplist" menu crashes too. It seems ok without these in rotation

Yeah that was my other suggestion

Ah it was down to inconsistent numbering in the end, seems ok now :-)

Make sure they all end in .nrf as well

I did it through the advanced options, deleted a map and then moved the others up so there wasn't a gap
