that is because valve updated TF2.
This skin needs to be remade into the game, so wait for version 3.7
Mayby the mini-sentry will be added :)

Good :D

I had the same problem, but I couldn´t see any sentrys. I hope this will be fixed soon.

When i was be on MVM with friend , in pda on sentry slot was be only missing texture . And when i placed sentry , there was be an normal sentry , not led .

That would be because some jerk at Valve felt it was just the smartest idea in the world to do something that a MASSIVE group of fans would not like: activating sv_pure 1. Now, most mods won't work in any valve server. Basically, this will be changed when they realize the obvious fact that nobody likes sv_pure at all. That might take awhile for them.

ofcourse, I didn't know about the sv_pure.
It is real pain in the a**.
I don't really use mods but I understand that this is horrible for manny users...
Hope that the "some jerk" will change it back.
