@erbmur I’m sorry, I didn’t think it would create such problem 
… I’m also late on the communication on that (big!) update, but I’ll do it this week end with all the changes 
The problem: you saved some options that do not exist anymore or has a different name.
Solution: open the options, change settings if that differs from your previous ones, close and that’s done!

About the update from “simple / complex” to “manhattan / subway”:
I felt like the “simple / complex” wire styles name were not intuitive at all, since you can’t guess what they’ll look like. Plus, “complex” could be interpreted as “complex to read” (which is not the case) and “simple” as “for beginner” (which again is not the case).
The new names “manhattan / subway” names help visualize what they’ll look like and has no connotation

Sorry again about the bad surprise :/, I’ll do the communication about what’s new and what’s fixed today or tomorrow
