Trainyard Map Texture Glitch

Trainyard, T13 lower left side ... there is this ladder access point to the lower tunnels ... from above it shows dirt, from below you can see out perfectly. This can be exploited by players below to shoot players looking down if you just make some noise and tempt them to come and look at the dirt. If this makes sense... should probably be fixed. lol 

This is a problem with this monument, I will try to fix it in the future
