"... I'm sorry I misled you with crappy information..."
Christian-Adrian, your ticket may not be solved as at now, but at least there's some breath of fresh air - I mean finding a CS who owns up there's a problem though no-one's able to tell what it is... At last you can tell that someone is doing some actual looking.
I've had occasion to wonder if my head is working right: saying on a ticket that this is amiss and someone says in response that things are meant to work like that and that nothing's been tampered with in an adverse manner...
And hey! I like the CS's sense of humor. I guess he/she even wasn't the originator of the 'crap' he fed you earlier on but a mere conduit for info'.
Sure, I agree with the last part. They really have the sense of a troll, I find myself a person hard to be trolled and to get a reaction from, but they did it. Congrats Upwork!
