Not exclusive to this update, I’ve noticed it in the past and forget to report it.
Basically it’s the same issue you had with the skip vote threshold settings. The Festive lights (the eating reindeer, leaping reindeer, etc) animation speed settings do not save and revert to 1.0 when condo is reloaded.
PS: A bunch of the “string” items (like garland) have settings panels like they’re lights instead of what they are.
This is now fixed in the next update.
Still broken after 0.17.6.0 update.
Follow up: The animation speed doesn’t save specifically.
Necro’ing to say this bug is back (or maybe wasn’t fixed idk). The animation speed for all the animated festival lights doesn’t save properly and on reload of a condo it’s always going at 1.0 speed (so quite fast).
I also noticed when you’re first placing one it claims the speed is set to 1.0, but it more matches the speed of 0.5. Once you reset it to 1.0 (or reload the condo) it’ll be going fast again. The only one that doesn’t seem to do this is the individual reindeer, it’s properly set to 0.5 when first placing, however it still jumps to 1.0 speed when reloading the condo.
I worded all of that horribly I’m sure so here’s a quick video of me showing both bugs:
Edit: It has been fixed!
Yeah 2 Christmases later this shit still ain’t been fixed. 
I took Mac’s solved tag off since it never was fixed, also edited the version number in title.
