Kerbals appear multiple times in the inventory view when seated on a EAS seat, allowing to duplicate stackable items
Consider the provided craft file
- Put a kerbal with stackable items (repair kits) in the Mk1 capsule
- EVA and seat on the EAS seat
=> the kerbal appears twice, their inventory too, allowing to duplicate the repair kits!!
There is also a desync with the kerbal's inventory when switching from the EAS seat to the Mk1 capsule but when coming back to the EAS, the kerbal finds back its inventory and can duplicate it!
