Just checked it, but I can't seem to find anything there of Larian neither.
Maybe they forgot to answer or to set an auto-reply, as you say. But then it would have gone wrong already more than a week ago, or something.
I can imagine they've got a lot of response, but on the other hand, I don't think you have THAT many who live so close nearby. It should be a bonus to be able to come often/fast, I would imagine, if not for now, then for later games.
I followed up with another mail, just because I thought maybe it went missing (could have gotten into their spam too, after all), but I've not gotten an answer on this latest one neither.
I'm not sure what to do now. I don't want to come over as too pushy. If they don't need me for testing, they don't need me. But without any sort of response, it's difficult to know if it's on purpose, or if something went wrong in the communication.
