Whenever I try to upgrade as a brood, the menu gets froze and I can't exit or move. The game doesn't freeze or anything. I checked the console and this is what it said:

[ERROR] gamemodes/morbusgame/gamemode/client/cl_vgui_util.lua:32: Tried to use invalid object (type Panel) (Object was NULL or not of the right type)
1. __newindex - [C]:-1
2. unknown - gamemodes/morbusgame/gamemode/client/cl_vgui_util.lua:32

I've searched all over the internet and couldn't find the solution to this issue. I don't know if it is fixable. It might just be the menu. I apologize if this is the wrong place to bring up this little bug I found. Anyone else here been encountering the problem? I heard that someone got something similar when they checked bodies, but that was in 2013.
