In the middle of manual clustering, no noticable problems. Suddenly, without any discernable action or reason (that I noticed at least), got the below error when selecting any cluster. Worked fine before on the same file, and before also on other files.
Didn't save the file after this occurance, restarted the kwik-GUI, and it worked again. (Will report back if this issue happens again after similar actions, i.e. after normal manual clustering)
edit: It now seems to happen after merging a couple of noise clusters with a bigger noise cluster. Undo-ing this action also stops the error from occurring. Oddly, redo-ing the action afterwards merges these noise clusters and does NOT give this error.
