Short description of error
------Objects displaced randomly (moved and rotated) after saving work file in .blend --------
Some objects are moving and rotating randomly when i re-open blender content saved file.
That's a crazy mistake for this PRO project, i'm in down way coz i've to repair always my saved file with this moved objects..
then i exported in .obj and re-import: this was OK .. nothing moved .. but then.. it re-appears till i saved normally in .blend !! shame.
Exact steps for others to reproduce the error
Based on a (as simple as possible) attached .blend file with minimum amount of steps
1 -- just move the "door moves alone_1" objet (sort of door in form of U).. rotate or move or the 2nd object "roof_moves_alone" which appears to have moved on test2 when i just move "door " !!!
1 bis -- just save file and re-open : objects (but not all) may have moved
Here to this file is before and after (on right) saved file !!
with marked points
2 -- i've put object "Door_moves_alone_1_repere" , which is a mark inside the "door moves alone" object that you see the effect.
3 -- i also saved a last time the file in .blend to upload for you: i screenshot it (Bug_mover_stade3.png) that when you open the file, you may see the moved objects ! as is
I expect you find something i did wrong, may be an add-on ? And thank you all ! and if you say when the error is found cheers !
