Installing a hp enhanced piece of armour resulted in the armour being given the hp bonus twice, resulting in excessive hp and weird display in the hud (due wraparoud I expect)
Note base armour is 135
135 x 1.5 == 202
135 x 1.5 x 1.5 = 303
I have a few homegrown mods installed, but nothing going anywhere near armour:
darker starscape backgrounds
installable ID cards
disabled mining computer
Confirmed in 1.8b3, bought and installed 30% enhanced Blast Plate in a Makayev dealer (in Rigel) and got much more then 30% but indeed double the amount. Did not need a shield in the arena until the slicer. The armour took damage, but could not be repaired (All stations complained about the armour being beyond their capability to repair) until its hitpoints were below the original +30% amount.
This is only when buying already enhanced armour. The previous (plasteel) armour it replaced was also enhanced 30% by applying Carbon Weaver nano's to it. This resulted in just 30%, not double.
Fixed in 1.8 Beta 4. Thank you!
