r1237 adds a "Scenario Instance" zone filter to the config window and fixes various bugs related to data collection, zone filtering and deletion in scenarios and fixes misclassification of solo-scenarios as raid.
I'll tag it release once I get feedback that it works as intended.
I can confirm that at least for me, it worked without a hitch. Just tried it as of 2 PM PST March 23rd. Thanks so much for your efforts to update! I missed Scenario readings. (:
