When I place one of the sprinklers from Seasons on any lot (residental and community lots) and turn it on, sims start playing in them and never stop. It happens both when I tell an active sim to play in the sprinklers or when active or NPC sims autonomously start playing in them. They queue up the "play in sprinkler" interaction, start it, and then it never ends. They will spend all day in a sprinkler, splashing about indefinitely. I hosted a party with my sims the other day and one party guest went to play with the sprinkler early on, and then got stuck in it for the rest of the party, they didn't leave when the other guests left, they stayed splashing in the sprinkler until the next morning, which was the point where I reset them to let them leave, and they promptly peed themselves right after being free of the sprinkler trap. Active sims can be made to stop sprinkler playing by actively cancelling the action. Just queuing up another interaction doesn't work, the sprinkler activity needs to be disrupted by the player or sims will keep doing it indefinitely.
The same thing happens to other summer activities that came with the seasons pack. Lounging in kiddie pools. Sims will start this activity, but not get out unless I cancel the lounge activity. Water balloon fights also seem to often run for an entire sim day without ending. For NPCs, sunbathing on loungers and towels seems also affected, NPCs sims on pool lots for example start sunbathing and then just never stop even when they glow red with sunburns. If it was just the occasional NPC burning I'd assume it's intentional and this NPC is just bad at sunbathing, but it's every single one of them. (This doesn't happen for active household sims.)
One of the recent patches changed the autonomy for these summer time activities, which is good, I was really chuffed about it. Finally my community water park pool lots get used properly! NPCs and active sims now use lawn slides, loungers, kiddie pools, balloon buckets and sprinklers! That's awesome because before they didn't do that. But I think something about the tuning is off. Maybe they don't have a time out or ending condition, I don't know. Maybe these activities should just run an hour or two and then end? For some reason they carry on indefinitely, and sims get stuck in them.
Happens on PC, latest patch, even with mods removed. I'm not entirely sure when this bug started, I play with the 28 days season length and it's now summer in my game, so for a good while previously sims didn't do these seasonal activities.
