[SE] NPCs keep opening and closing the Onsen locker repeatedly

It was in a normal gym. 

This happened when my sims were using the lockers on a Rec Center lot

I am getting this bug on all lots that have lockers since the latest patch.

My active sim can use the lockers fine, but townies are autonomously opening and closing lockers in an endless loop.

I have seen it happen in a Gym, Recreation Center, and a Pool venue.

Same thing happened to me but in my residential lot with the spa day locker. Sims would come for a party and stay opening and closing the locker in an endless loop. I had to reset them with cheats to get them to leave. 

not sure if it's going to help but I observed when these sims arrived to the lot, they will go to the locker to change to their everyday outfit and then they're gonna open and close nonstop even I tried reset objects (both locker and sims). 

normally, for Spa lot, sims will change to the robe. For Onsen lot, sims will change to swimwear as far as I have played. For Gym lot, they don't have to change outfit at the locker object when firstly arrived but they will wear a towel after shower. So I guess there's something missing in routing here. 

I tried logging with a diagnostic mod (see below) and found that it seems like the Locker Door Close is running and being queued at the same time (line 18 and 20).

The unplayed Sim (Emilia Ernest in my game) had just arrived the lot and it seems like it was coded they will automatically leave the lot after state Locker Spa Guest Change Into Everyday (line 21). Sim never gets change, they just arrived, they are in Everyday outfit all the time.

That's why the issue is the same as I found with the locker objects from Spa Day pack at a Spa lot type as well. So you should add Spa Day pack tag for this bug.

I also use Sim Control Hub mod to control an unplayed sim as well. I found the queue was "Change into Robe" and it went through but Sim changed to swimwear and play along the situation in onsen lot as expected (take shower, relax in hot spring and so on). 

Hope this helps.
