Invalid Idlers room glitch thing... again!

I were playing on the Achievement/Idle servers, and while trying to get some kills to my s. scattergun I have noticed an invisible metal wall. I, and people on the server had considered that it might have been an glitched sentry or something, but after watching the demo, I found out what it really is. Well, basicly it's some bugged out weapon props, which are invisible. Map that it have happened on was : achievement_apg_remade9j

DEMO: http://puu.sh/afQz7/1ee747bb92.dem

 

I'd guess this was a glitch with the map, nothing n0name can really do tbh.

 

Not really, it had never occured before, and I am playing on that map for 3 years.
It might have been the idlers room plugin issue, since that's the only new thing there.

 

ah ok :3
