bug [42.3.1] [rev:26566] Attacking zombies with a spear through a fence leaves player stuck in combat stance.

[OverDoseZA]

Version: [42.3.1]
Mode: [Singleplayer]
Server settings: [N/A]
Mods: [Several]
Save: [Existing B42 Save]
Reproduction steps:
1. Start game.
2. Load existing B42 save game.
3. Equip a spear (in my instance a spear with metal head - not sure if other types of spears cause same issue).
4. Approach a fence where zombies can't track to your location (my location is at the Ekron fire station - with Ekron Community College behind me).
5. Start killing zombies with spear through the fence while in combat stance.
6. At some point the game will make the attack sound but not actually attack (00:18s in video) then player stops being able to attack zopmbies and will remain stuck in combat stance.
7. No other actions can be performed, or menus be accessed when stuck in the combat stance.
8. The only way to get it to stop is to exit back to the main menu.
9. Once the above steps are repeated, it results in being stuck in combat stance.
10. Other melee weapons (I only tried a knife) being used through the fence do not result in the above.

I initially thought it was my wireless mouse acting up and I tried a wired one and the issue happens even with that.
