Yep, some players felt a bit naked without weapons in AncientWorld.
I can't recall a crash problem with the end in this map. Well, more than 10 years have passed since I played Zora's maps the last time.
My first thought on this is a similar problem which also occured in the cat-map (sorry, can't remember the full name of that map right now), but it seems to differ a bit from the problem you described here.
Currently I'm a bit limited with the loss of my "home" system. Full testing like in the past is not possible right now. Also I've a weird problem to get a fully working client with which I could connect to the servers. For some reason not all servers are shown in the AllServers list.
My first thought was a Firewall or Antivir problem, but if that would be the case, then I wouldn't see any servers in the list at all.
From the Newbies servers I can only see 3 or 4, but the rest are not shown, no matter what I try.
The XperienceCoop server is in the list, so I should be able to connect to that server. But I must download every file needed for that server. And I need someone to play the map with, preferably someone who knows the map and end it. If my client should crash then, I can get a logfile of it. Maybe that gives a hint to the problem.
