It will be fixed in the upcoming v1.1 update.

Most hintstrings are compiled to the FF - if you want to change them you have to find where they are referenced in a setHintString and change it from a &string reference to a quote literal.

The wall weapon hinstrings are the only hintstrings which aren't compiled to an str.

Okay thanks for the speedy reply.

I guess I can put up for the weird sprint for now as long as I get the Thundergun in my map.

I want to put Porter's X2 Ray Gun on the wall but there is no hint string. What file do I need to edit to change this?

I also made it in my map where there are debris on top of a trap door. When you buy the debris it clears a path to the ladder that leads to the roof. It also clears a path to the trap door that leads to the basement. I made it so you can only buy the trap door after the debris. I also had it so the hint sting for the door only appeared after you bought the debris, but when I installed UGX the hint string was there even before you bought he debris. Do you know what causes this and/or how to fix it?

Note that my script still partially works even with UGX because you still can't buy the door before the debris even though the hint string is there.

hint_string = get_weapon_hint( weapon_spawns[i].zombie_weapon_upgrade ); 
cost = get_weapon_cost( weapon_spawns[i].zombie_weapon_upgrade ); 
ammo = get_ammo_cost( weapon_spawns[i].zombie_weapon_upgrade ); 
upgraded_ammo = get_upgraded_ammo_cost( weapon_spawns[i].zombie_weapon_upgrade ); 
weapon_spawns[i] SetHintString( "Press &&1 to buy " + hint_string + " [Cost: " + cost + ", Ammo: " + ammo + ", Upgraded: " + upgraded_ammo + "]" ); 

Check your script again, because UGX Mod does not modify the blockers/debris script. To add a weapon hintstring, check _zombiemode_weapons.gsc. Weapon hinstrings are set on line 651, and they are adaptive to any weapon. If you don't see a hintstring then it means either its name, price, or ammo price are undefined:
