Not sure if I'm just special or there is an actual bug, but it seems like there is a maximum amount of bonuses that can be applied.
I'm currently in Tier 3 (Max 4 augments): and have the following Augments for clothing
1. Excellent Explorer:
* Speed +++
* Stamina Regeneration +++
1. Beserker Augment:
* Injury Resistance +++
* Health Regeneration +++
1. Refined Magick:
* Ice, Fire, Maleficium and Poision Resistance +++
1. Excellent Tailor:
* Max Health +++
* Max Stamina +++
When I create armor using, Cloth (Tier 3 Holt Bloom), Thead (Tier 3 Cinder Strands) and Buttons (Steel), it show me the correct stats in the preview, but when I obtain the crafted Item, the stats are lower and I'm missing the "Max Health +++" and Max "Stamina +++" when I inspect the item...
Am I missing something here?
EDIT: It doesn't seem to be a max, because I just added a T3 infusion on top of it and it worked just fine, maybe the Excellent Tailor is just bugged.
Extra info, I noticed some strange changes in stats while going to the next tier, because the numbers changed in different amount than wat was the actual difference between the armors. I appears that the infusions are invisible but they are actually there. Because a piece of armor with the invisible health +++ that has a natural 30 max health, gives more max health when you equip it. So the stats are actually there, but they are not applied..
Noticed the same with a workbench and umbrella.
