Sorry Robert, a correction: RoonOS was updated to Build 254 and Roon proper was updated to Build 1148 at least. The OP has both of those. Seems fine.
There was another update to RoonServer Build 1154 announced, but I am not sure if everyone received it - some posted they didn’t and there was some speculation if it was pulled due to a memory leak that was reported in some thread, but no official comments from Roonlabs. (I’m on earlyaccess so can’t say)
