First off I want to mention you @Green Storm so you can notice it soon enough, and with that being said let's go straight to the point.
1. The compound system (shift + P) is available for months, and it is still bugged.
The bonuses it provides are not applied/added/shown in F2 stats.
2. The equipment resonance (2nd icon in the bottom row in the inventory) is also available for months and still bugged.
The bonuses it provides are not applied/added/shown in F2 stats.
3. The skystealer accessories gain a special bonus (effect) when upgraded to +6 and higher, and this is bugged as well.
The bonuses it provides are not applied/added/shown in F2 stats. On top of that, the bonuses are not shown on the item's description in F2.
4. The newest soul shields are also bugged. They are not shown in F2 (not a new bug so not a surprise, and while at it, octagonal gems have the same issue). In addiction, the mystic stat is not shown in F2 on any soul shield (and the mystic bonus it provides is not applied/added/shown in F2 stats).
But that's not all. There's another big issue. Let's say that I have one soul shield with critical and mystic, and then another with mystic and critical. They have the same stats, but you cannot use any of them to increase the stats on each other because the stats are in different bars/rows.
5. While in F8 on the Demonsbane tab, when you switch to dungeon tab, it automatically sets the difficulty to normal (should be set on easy, as when you enter F8).
6. According to some informations - we're about to get a Celestial Basin rework which means that monsters will have more HP, and that's not a bad thing, except for the fact that they will have too much. Hopefully there will be an adjustment for our version.
Please make sure that these things get fixed asap as more and more things are not added to F2 stats...
Have a good weekend.
