Retired boosts only allowing one

So I played the crash today (Kraven vs. BP) and I still had 10 of the retired Kraven damage boosts. However when I went to use them it only allowed me to select one. The ‘Boost More’ button didn’t appear.

Hi Loosie,

This is the intended behavior for Retired Boosts, and they can only be equipped one at a time.

Hi Tombstone, when did this change? I used to be able to stack them up to 5 times like the regular damage boosts.
