Summary

SO just updated to 7, and noticed that when continuing a groom i was working on, by continuing to plant new guides, it simply wont plant any new ones.

Also when i make a new groom, plant a new guide by hand and use the "edit guides by control points" function, sooner or later the undo just stops working.

When i reinstall 6, all problems dissapear, i can plant the guides again and undo keeps working.
