Sure it's a fast and easy quick fix.
But the problem is that well, isn't that big or fixes anything problematic at all. It only fixes some text typos and thats all. Most people don't read item descriptions and mostly go for the stats for damage it deals and how much power it consumes, and if they see any typo in the description they kinda skip that.
Only way to fix that is well, editing the game files by modifying the descriptions. But if a such update of 1.0.3 or 1.0.2555 comes out with a Unity Engine update that some people want, maybe there could be some text typo fixes made by the devs.
So, in other words. Tynan and some devs from ludeon do kinda walk around the forums from time to time. But they can't miss em but they still view it as low priority in their lists. Unless they do listen.
Updating Unity for multithreading isn't something that shouldn't be low and has to be somewhere in between high or medium priority with a couple of tweaks, but i understand why it takes that long or it won't if it would break saves..
