It's nearly impossible to read the font in the Weapon Designer Menu, it's very grey.

This is known, i'm not sure why it occurs either but I'll look into fixing it at some point.

Everytime I remove a pewpew weapon that is welded to a prop, it crashes my game.

evry time i shoot a large almost ghostly "bomb" apears and it makes it realy laggy

I undo pewpew, Garrysmod shutdown

Wish i had more information but there are just occasional and random crashes while using PewPew Not sure what is causing it or how to find out. If you know how to find out if there is a crash log or something just let me know ill be happy to post it for ya

A bunch of weapons suddenly stopped working after i joined a server that also had pewpew..

Whenever I undo a PewPew weapon, it immediately crashes the game

Whenever I press Z and undo any pewpew thing, game crashes.
Font in designer menu is unreadable.
Sometimes it starts spamming console errors for no reason (even when no pewpew weapon is placed).

A recent GMod update seems to have broken a few things. Try switching GMod to the dev branch and let me know if these issues still happen.

Yeah; that seems to have fixed the issue. Guess ill leave that on for the moment!

I'd fix it in the addon if I could but the issue is purely with GMod on that. Oh well!

Placing a dupe with pewpew weapons causes lua errors, breaks all constraints, and is unable to be removed

If you would please take a look at wiring not carrying over when you dupe a pewpew item. Adv dupe 1 and 2 present the same problem. Could it be that they are unwiring as they setup their wire inputs?

I'm not sure, as it works for me and everyone that I know uses it.
