Please make the suit of armor register as an armor and not a backpack as using a mod like extra equip slots+3 makes it so you can equip the armor in the backpack slot as well as another armor in your body/head slot, meaning 3 possible armors at once. While this is amazing for sharing armor durability and overall length of protection, it does mean that you drop whatever backpack you're using at the time in favor of Undyne's armor. A little annoying since I got the mod specifically to use a backpack with armor, so by having her armor register as a backpack, it makes the mod useless.

Also there's still the glitch where she respawns with like a TON of her determination in the meter already which can put her in an infinite death loop if you just keep pressing her transformation key. The meter should always restart at 0 when she revives, not 2500 or whatever it was.
