fixjoint parts move (after fixing and loosening background)
short story = stuff moves after i fix and loosen a fixjoint to background
-----------------
full story =
hi im pretty new to algodoo but i tried to wait firing all my nooby questions, so i played it for 2 weeeks now and discovered most answers to my questions trough trial and error by myself.
but now i found a thing that looks like a bug = i made a train wagon with doors and wheels and springs and windows ... so with lots of fixjoints to hold the piece together. sometimes while i work on it i use 1 fixjoint to fix it to the background , in pause or play, but now i discovered many small pieces move , although they were fixjoint connected
i thought i accidently dragged the main shape with move tool, what sometimes was the case, but now i discovered that stuff moves a tiny bit every time after i delete a fixjoint with which i fixed my trainwagon to the background. i did it as a test 10 times fix / loose in a row and i saw many parts (not all thou) moving a tiny bit to the right, SO WEIRD, and obviously very frustrating. and some parts move even more than other parts. and the place where i fixjoint the wagon is just a plain piece steel 1 layer . the wagon is larger than real size about 30 meters.
anyone knows if this is a bug or am i doing something wrong? either way what can i do to solve/prevent it? i hope someone can help me because this thingy really destroys my algodoo fun.

Hey,beamybeans.
Did you use any "Glue to background" and "Glue Together" geometry actions?
Well, It's not recommended to use any "Glue To Background" or "Glue Together" geometry actions when you're using the fixate tool to prevent bad stuff from happening

Re: fixjoint parts move (after fixing and loosening background)
ok here 2 saves = before and after
before http://www.algodoo.com/algobox/details.php?id=109131
after http://www.algodoo.com/algobox/details.php?id=109133
i notice now the stuff moves to left instead of right, look at 1 stray star of the usa flag, the laser, some window parts etc. its not only graphic bug the stuff also reacts according to their new position

Re: fixjoint parts move (after fixing and loosening background)
your X position is very high, 6.5 kilometers from the origin, such large distances experience rounding issues during some operations, such errors are part of the fundamental float types that are used in Algodoo, and they are not consistent in any form. These errors are the reason why killplanes are located 1km from the origin. Beyond them, well, Here be Dragons.

oh, yea makes sense the way you explain it. i didnt know there is a central point / origin. waw i hope this is the cause then i can avoid the bug. THANX a lot
========================================
edit = yes i just tested it i copied the train into a new default empty scene, not in my adjusted saved empty scene (where i probably messed with stuff)
it works the bug is gone YAAAAAAAAAAAAAAAAAAY
