After analising this assert (see below) I think this is the problem:
The droid is in status MOVEPOINTTOPOINT, but it's target X and target Y
are it's current position.
This results in move.c:3804 moveGetDirection(psDroid, &tx,&ty); to set
tx and ty to NAN
this results in tangle = vectorToAngle(tx,ty); to return NAN and thus
moveDir is NAN
This NAN moveDir gets turned into an angle of -2147483648.000000
A possible solution (in the patch) would be to check the coordinates to
be different from it's current position, but I guess someone with more
insight in the move-code should be able to come up with a more elegant
solution.
