After the February update, my rules seem to have entered a chaotic state. Rules disappearing. Rules dropping internal states.
It looks like it may just be me.
Thanks.
I haven’t seen any bug reports relating to this… Sounds rather strange.
yeah, it’s pretty odd. I’ve been watching here for comments.
I try to not have problems that others haven’t already solved… 
Maybe try to rebuild your rules, or check your SDCard for errors. I have 21 rules and all survived the update just fine. Maybe just try making a small edit and resaving them.
