Game Version: 2.2.4p
Martial Excellence: 1.0.5.2
Tabletop Tweaks Base: 2.6.3
The mod works well in this version of the game. However Vicious Stomp appears to only be selectable as a Fighter bonus combat feat. It does not appear in feat lists during level-ups otherwise. Other feats added by this mod do not have this same issue, so there appears to be something different about Vicious Stomp specifically. Even after disabling Tabletop Tweaks (The only mod which alters Feat visibility in my list) this issue persists.
Thank you for reporting this but I'm not really intending to maintain the mod anymore. However, as a bandaid fix you can add Vicious Stomp to the character manually using toybox.
