- added a workaround for a crashing condition in FThinkerIterator.
It can actually happen that the thinker chain gets broken if an actor being iterated happens to destroy the immediately following actor in the chain as well. In that case both actors lose their chain links and the iterator cannot advance any further, the only solution to avoid a crash is to terminate the iteration of the current list.
