Game stuttering after last update

[Alunny]

After I updated last night the game won't run right. It stops and starts, freezing up and stuttering. It's really annoying and removing all my mods and restarting hasn't helped . Is there something I can do?

Here's a video. No mods, new map. Save file here: https://drive.google.com/file/d/1R8LlkWn_hLM4oaBVu9F6lfF7keVa6FQv/view?usp=sharing

I have everything except the new island expansion.

There was no update to this game last night? Or are you referring to some other update, Windows perhaps?

Note there is a reported bug that sounds like this, that only happens when you are building foundations for a large building. It apparently comes good when the foundations are completed. Could that be it?

The update was from July 2nd, I use GOG. Windows 10 64 bit.

I've done some further testing it may be related to that. I don't know what is triggering it but on a new map I've had no problems even when the foundations were going in and were the same size, though one set of them broke and had to be redrawn. On that first map in the video I only had issues once I put in janitors. Hopefully my save file can help shed some light and if not hopefully your bug fix release for the foundation bug and the problems people are having with janitors solves it.

Thank you so much for responding .
