Ideas
Two more questions then
- Does it matter if you assign the left side or the right side ? Is it always the wrong side ?
- If you re-assign, does it still not work (like assign someone else to that side, then switch back).
Yes to both occasions.
I first assigned Sim A who I had been experienced this with the right side instead and Sim B the left side, and Sim A would still walk to the right side.
After, I re-assigned so gave left side to Sim A and right side back to Sim B and Sim A would still first attempt autonomously to go to the right.
Thirdly I even switched the bed to see if it was behaviour tied to a specific furniture and the problem still persisted even on this new bed.
And lastly the issue doesn't seem to be just this one Sim being affected but afterwards I changed control exclusively to Sim B and he would also always choose the right side of bed first unless the right side is occupied which makes them to cancel the action and either trying to sleep somewhere else (such as a free sofa) or to walk to the left side that was actually assigned to them.
