Just a "were aware of the issues but don't have a fix" or "we're currently looking into it" or even just "we don't care, stop asking" would be nice. I mean, we're well into S15 now and several weeks since a dev responded to this thread as well as and still unable to filter builds by Has Spell and still getting the admittedly mostly harmless but annoying undefined messages when not selecting gear when filtering. Would be nice to get any kind of response at this point.
Sorry for the silence, we are working on a solution. No ETA
