Sometimes (like 1 out of 10) if I unlink a pair of locos, the one that isn't accessing the Unlink gets "locked". By locked I mean the loco screen comes up, you see the loco and the tools and info icons, but the buttons dont come up. And the radio button stays gray, like when you try to activate a loco but that loco is not turned on, even tho the locked unit is turned on. It seems to affect trailing loco. I have to turn all my locos then unlink any that are linked, and at that point the "locked" unit will activate.
