I've used it before without major problems but for one particular scene it just wont comply. I need the head and neck of a tortoise (I drew it in flash) to slowly angle towards the ground. It needs to be smooth (impossible to do frame by frame). When I apply the bone tool the graphics change so that some lines around the tortoise's mouth become thicker and some become bumpy and irregular. This has happened before but the problem went away after rubbing out some parts and redrawing them (no idea why that made a difference but it worked so who cares). Well that isn't working this time at all. If it wasn't for this, the bone tool would otherwise be working fine (I can still move it where I need to) Please help, thanks.
