This glitch is when a user with the Wemans mod, or Bird Mod or any other mod that has the bird animation uses it to near instantly reload. The fix is a simple script where it unwields the weapon when the animation is used.
module_scripts.py, search this line: (eq,":action_type",player_action_surrender),
If you have WSE, add:
(agent_cancel_current_animation, ":player_agent", 1),
after
(eq,":action",music_type_stop)
If you don't have WSE, you could add this:
(try_begin),
(agent_get_attack_action, ":aa", ":player_agent"),
(eq, ":aa", 5), #reloading
(agent_set_wielded_item,":player_agent",-1),
(try_end),
It just unwields the weapon, not very elegant, but it works
