Fixjoint doesn't fixate

[Rideg]

Well the title says pretty much all. I start the scene everything is fixated as ist should be but when I make a change the fixjoint doesn't do what they're supposed to do.

I can make any progress with this bug.

This occured in Algodoo v1.7.1 but I'm gonna download the latest beta right now.

Can you give a specific example? I won't be able to fix this if I can't reproduce it

well I grouped some objects with fixjoints (I grouped the fixjoints and objects) and when I deleted the grouped one, some other fixjoints that didn't have anything to do with the group was deleted aswell. they wasn't attached to the grouped object infact they weren't even close. I didn't use any "glue to object".

I think it has something to do with the grouping because when I "ungrouped" them it worked.
I don't have the scene left. I bypassed this obstacle using the upper solution.

I've tried to remake this using a similar scene but I can't get the bug to work again.
