if using arc emu, then run this on the worlddb:
Code:
update playercreateinfo set taximask="4294967295 4294967295 4294967295 4294967295 4294967295 4294967295 4294967295 4294967295 4294967295 4294967295 4294967295 4294967295";
and this on the charactersdb:
Code:
update characters set taximask="4294967295 4294967295 4294967295 4294967295 4294967295 4294967295 4294967295 4294967295 4294967295 4294967295 4294967295 4294967295";
Costs are, as Harry so aptly pointed out, not as easy to edit.
Hope this helps!
