This still happens when the host gets Party no longer valid [Network Error 400]

Can a player who got that error 400 post their player ID and timestamp when they got it

@SimGuruMaaikeThe problem was never gone. If players enter a party too often, the party crashs. Nothing has changed since March 2018 on this issue. At the beginning of the year the limit was set higher till the party crashs...

I just experienced this issue. My steps were:

playing on iphone 
1. was doing some event management

2. Attended a friend’s party

3. More event management and started having a baby with one of my 4 sims

4. went and did irl things for a couple hours

5. came back

result:

Immediately i noticed that my sims had lost progress. The sim that was having a baby was now back to being marked as having finished an event instead.

I started checking events then I, foolishly perhaps, made the mistake of checking the party and tried to send a sim back into it.

I hung on a loading screen when i gave up and killed the app and came back in the button to join party was grayed out. It says i already did all my parties for today.

no more time travel, ok server guys?
