I registered here just to bump this post - there are all sorts of complaints elsewhere (Reddit, etc) so please don't think that a lack of discussion here means this isn't impacting a lot of people.
As a first time player, not being able to use a *massive* chunk of equipment is really ruining the game. There are countless situations where you only meet the stat requirement to equip something due to stats gained from other equipped armor pieces, and this bug means that like 1/3 of armor I should be able to use is just worthless.
Again - when viewing equipment, if you meet the stat requirement to equip a piece of armor due to stats gained from another (ie, "requirement met due to equipped items" message is shown in the tooltip), it will not work. The tooltip itself will be normal with no red warning text and tells you that you can equip it, but you're unable to do so and the "equip" button prompt at the bottom is greyed out.
I'm really hoping you guys still do bug fixes for this title - I get you're working on a new game, which I am very excited about, but DOS2 is my first time playing a Divinity game (I'm playing it purely because of your Divinity announcement) and I'd imagine there will be tons of others playing it for the exact same reason - please, please fix this. Gear is such a huge part of games like this and not being able to use so much of it really sucks.
