Giant Reign drop out

can anybody offer any reason(s) what would cause the rear dropout on a reign to keep snapping ??

thanks

This used to happen to mine. Think I went through five or six before it stopped! Reckon it was down to chain being too short or back end possibly loose.
chain being to short so when the bike bottoms out its pulling the mech forwards and ripping off the dropout. Remove the shock and check the chain length at bottom out to check this
thanks hopefully i can get to my mate before he throws the bike off a cliff having broken 4 in as many spins
