ULib\modules\UMaps/init.lua:252:attept to call feild 'concommand'' (a nill value) off a fresh install with an edited umaps maps file.
happens after UMaps.lua loads.
havn't tested if it causes the addon to fail yet, but i will return with news if it does
EDIT: whoops, didnt see this was so old. but still, could be usefull as i dont know of any other map cycler.
