This bug may have been described ar rare in the update thread, yet I also encountered it.
The versions 1.28.2.64 and 65 revealed very prone to brutally crash to desktop on my system, especially in loaded areas. So brutal that I'm not even sure a crash log could be sent. Quite annoying. However, the 1.28.2.66 is rock stable again. Good job, Henri.
I hope the 1.28.2.67 released today will follow the same path to reliability. We will soon find out...
