I would not consider that 'cheating' since a game glitch forced you into a dead-end situation
In my old WoW days, i remember being several times stuck in the 'environment' and the 'GameMasters' were informed, and they ehm..unstuck (sic!) me
Once my buddy ended up stuck in a tree, he informed the gamemaster who somewhat later whispered him 'hello, you still suck?' heeh he mispelled 'stuck'. It was a collective laugh riot, enough said
