I've decided to make the aoezone community aware of these bugs because I reported this bug, at least for the Goths, before the latest patch over on the official AoE forums but the thread got no replies. After the bug still wasn't fixed (lots of people don't use technology hotkeys, sure, but this has gotta be an easy bug to fix!) I made another thread about it ... still wtih no replies. I then decided to post a video showcasing the bugs to make it absolutely clear.
I'm still worried I'll get no repiles over there though ... so I thought I'd let the lovely aoezone community know instead. Sure, I understand that this might not apply to a lot of people because not many people are using the hotkeys for the technologies. But it will apply to some people and (hopefully) increasingly more in the future as I can imagine the pros will get used to having hotkeys for techs eventually (okay, maybe not our Lord DauT, but people like Viper, etc).
And ... it already applies to me. I've gotten quite good at changing and adapting to new hotkey setups (despite being very bad at the game, as a 14xx Voobly player).... so I already use hotkeys for all the techs. Hence why I noticed both bugs.
