Running on my HO layout the other day, I first unlinked two locos. Trying to link a new consist, I was denied including one of those LM3-equipped locos, repeatedly seeing the message that it was already in another consist even though the loco screen showed it unlinked. All software was up to date. I tried setting it off the track for a few minutes, even went so far as to reboot the layout, but nothing worked.
Until it did.
Has anyone else experienced these glitches that come and go? Or did I miss something?
