Failed to load any attacks for melee weapon pipehammer. Old problem, anyone know how to fix it?

It's fun, but too easy. The hard part, is the immediate start (escape) - when zombies, almost always seem to be right on you, which can make difficulties above normal super rough going the first 1-3min of the map start. After that, the objectives seem to help the map even out so quickly, and easily, that it's relatively straight forward, to get to the ending and be done, within 15-20min. IN fact, after 3 starts (because zombies ate our faces off in the first 1-3min each time we spawned) the 4th try we were able to get passed, pic k up some weapons and find eachother and march through pretty straight-forwardly (3 people total). Solo was about the same. A suggestion is creating some kind of crescendo-like events on some of the objectives, and potentially adding some special events to certain objecives or just some of the lore items (the recording was cool, which there'd been more to that, in the map, as well).

Any comments or reviews for our last update?

I'm trying to use this in an online server I own. I've uploaded the .vbk and the sound one to the server but when I do "rcon changelevel session 9" in the console, it says no map found for "session.bsp". So I tried to change the .vbk name to ce_session9.vbk and try doing "rcon changelevel ce_session9" but still no luck.

UPDATE ON THE WAY.... INCLUDING HUNTED MODE
