Fistly, sorry for my bad english, but I will try to make it clear

I've been using this mod for a long time and never had a problem. And many thanks to the Raks for a wonderful mod.
However, in the last game I ran into a problem.
1. My choice of color for the plan has disappeared.
2. Using the normal planning tool, I got a bright selection ( https://ibb.co/pnPZkps ). It was inconvenient. But since I have other planning tools (Planning Extended), I decided I didn't have to worry and not to change anything with mods in this game, having finished playing this game. It simply without using More planning.

My mistake was that at some point I decided to mark a few places that seemed important to me - an ancient danger, for example.

As it turned out, if you mark a tile, and then remove the marker quickly (for example, digging up this tiles), then there are no problems. But if somewhere in the corner of the map there were such marks for a couple of in game months ...
When the marked this tile enters the view of the screen - TPS falls catastrophically. Digging up the tile or building it there doesn't help. I destroyed some of these marks through the developer mode, but three remained.

When you hover the screen over them, the CPU usage increases from 12 to 60 percent! T: Destroy and Clean Area (rect) leads to freezing.

It seems to me (based on the specific color of the cells - https://ibb.co/BzXFd12 ) that the problem is that the game constantly adds another mark of the plan to the tile and repeats this many times.

Removing the mod doesn't help.

p.s. Reading the comments here I saw that some problems of Jet are related to Dubs Hygiene. It is interesting that the game I started is the first one where I also use this mod. May be Hygiene and More Planning had a conflict?
