sometimes trajectory poops out a lot of errors when hitting barricades with zombies hitting it. Not always happening but it won't shoot out new bullets unless you travel a little further away from the area

I checked it and found typo in code. Thanks for your reporting.
I'll fix it in next update.

Are you playing in MP? If so, are you the host?
+ Are the mods you're using really same as the list above?

I'm asking this because that errors are caused by problem with Gunfighter options.
I've put a line of code for checking whether Gunfighter options set properly.
If there's problem with Gunfighter options, there will be exact same errors as you reported.

1. Not using Mod Options mod
2. Using Gunfighter server template
↑ These are the common reasons for that errors, but there's 'modoptions' on your mod list and also Gunfighter server template doesn't seem to be on your list. Therefore, that error should not occur unless you modified Gunfighter option file personally.

Yeah I'm playing in multiplayer. This is on a dedicated server. I didn't modify the gunfighter option file, only though the sandbox options menu.

I saw the list above but ask this just in case, there's 'Mod Options' mod in your sever?

When im level up ex. on defend wall, i cannot shoot to zombies. 100% miss. Hits are only on same level as opponent is. (i encountered this problem after latest updates)

Which version you're using? I tested w/ Normal and Z versions but couldn't find the problem.
If you're using Normoal or Vanilla version, make sure you change your aim level and get close enough to the edge of the floor. (If your target is close to the wall) Like this[i.imgur.com].

Oh... there's a typo in the code.. Thanks for reporting.
Gonna fix this in the next update. (In a few days)

May I ask what was the typo? I could not find it

Edit: oh gosh, was it the single dot instead of double dot? Coding can be so harsh...

...

It's kind of compatibility issue.

1. When player shoots a crossbow, crossbow mod saves some data as weapon's modData.
2. This mod do not use vanilla shooting system, so manually triggers OnWeaponHitCharacter event when projectile hits target.
3. When this mod triggers OnWeaponHitCharacter event, it makes a temporary script item and pass it as an argument to event.
4. When OnWeaponHitCharacter event triggered (when target get shot by crossbows in that mod), mod do some tasks w/ modData above.
4. The modData of crossbow mod are saved in the weapon object player holding in hands and of course, the temporary script item created by this mod do not have it.

This is why that error occurs.

Thanks for reporting and gonna try to fix it in the next update.

i found that the bow and arrow mod conflicts with this mod, when aiming with any bow it says "out of range" don't matter where the cursor is, but it still let me shoot arrows
