Script Errors

Not sure if this is fixable, but I thought I'd post it here anyway in case it was.

The first script error seems to spam console whenever it comes up, and when it happened, I was just switching between players while spectating. Here's the error:

[ERROR]
1. unknown - [C]:-1

Error in hook CalcView: lua/weapons/fas2_base/cl_calcview.lua:10: Tried to use a NULL entity!
stack traceback:
[C]: in function 'LookupAttachment'
lua/weapons/fas2_base/cl_calcview.lua:10: in function 'func'
gamemodes/base/gamemode/cl_init.lua:380: in function <gamemodes/base/gamemode/cl_init.lua:347>
[C]: in function '‌‎‬‪‭'

My guess is it has someting to do with the weapons pack. Either something wasn't mounted/pasted correctly or the code was messed up initially and it's trying to call on an entity that was never there to begin with.

Here is the second error that came up. This one did not spam console, but came up when I took out a weapon:

[ERROR]
1. unknown - [C]:-1

Error in hook PostDrawViewModel: lua/weapons/fas2_base/cl_model.lua:733: bad argument #1 to 'ipairs' (table expected, got nil)
stack traceback:
[C]: in function 'ipairs'
lua/weapons/fas2_base/cl_model.lua:733: in function 'Draw3D2DCamera'
lua/weapons/fas2_base/cl_model.lua:605: in function <lua/weapons/fas2_base/cl_model.lua:138>
[C]: in function '‌‎‬‪‭'

This is probably something messed up with the model.

 

The hell does a browser plug-in have to do with script errors in Garry's Mod?
