I have a simple RL transition that gradually changes my kitchen lights from daylight white to warm white. It's triggered using the activator device in a RM rule that runs at evening. The RM rule makes sure that the kitchen lights are at 100% before triggering the transition, so only the bulb color should change.
After a few issues early on, it's worked as intended for a while now. Until tonight. When the transition is triggered, the lights are dimmed to 4%, the level is then transitioned until it reaches 100%, and then the color is changed immediately with no transition. I can recreate this. I haven't changed anything in either RL or RM. The only thing I did was upgrade to 2.3.4.114. I tried the update to 2.3.4.115, but I can still recreate this.
ETA: I have two of these transition scenes, and the other also did similarly wonky things.
Here's the RL app:
And here's the first part of the log (I'll spare you the entire transition):
Here's the end of the transition showing the sudden color change.
