Thanks for replying.
The map in the link you posted is from 2014, this version is from 2017. I'm not sure an even older version is going to work any better, especially since the 5/4/18 update. I'll try it though, maybe I'll get lucky.
Thanks again.

Hi mister, I'd highly suggest ya to use another version of this map.
I'm not the creator and not skilled enough to rework it.

Check this one:

Hope this will fix your issues.

Here's a screenshot of some of the error strings.

Sorry, ran out of room in the other message.
Is there any way to fix these errors? It's a fun map, but going from ~200fps to 19-20fps constantly is a real buzz kill.

A couple of sound errors keep spamming the console and killing my frame rates.
