Comment (by Lars Aksel Opsahl):

 Thanks very nice job I tested a couple of jobs this night

 For test number one before the fix we had topology errors in 224 off 2328
 cells after the fix we 1 topology error. And that error does not seem to
 cause any spatial bugs.

 For number 2 we had 13 errors and after this fix all was gone.
