I have been reading the pocketmine forums and i have noticed people having problems loading worlds. well I have the fix, its something to do with the 0.15.0 update with pocketmine or something not converting blocks that are not supported in MCPE over MCPC to air blocks which is what it originally did. so now blocks that are not supported in MCPE will crash the server on a join. so now i have one last question.. how to i take out un-supported blocks in mcpe out of a mcpc map?
