[Nakor]

It does not happen everytime and I cannot find a scenario to reproduce it but it happens quite often:

I may have a scenario. Once you have begun to add or remove relations, that behavior happens at pretty much any merge, combine, undo, redo operation.

This should be fixed in r2487, you're working with 2485.
