Hi,
I got this error in the Pd console and all sliders and vumeters in the patch stopped working (while toggles, numberboxes and other gui elements still worked):
(Tcl) INVALID COMMAND NAME: invalid command name ".c" while executing ".c coords a7e9d8RCOVER 869 255 877 333" ("uplevel" body line 1) invoked from within "uplevel #0 $cmd_from_pd"
I have no idea what triggered this, I was using a rather complex patch (which never gave me such an issue up to 0.42.5)
