I am not sure if this effected 4.1 also (I am pretty sure it did but I could find any servers that matched the criteria) but when viewing servers in the UrT Server Browser if you click on a servers info and that server happens to have an ip that fills every block ( xxx.xxx.xxx.xxx:2796) it leaves off the last number of the port since there is not enough room allocated.
I'm sure you have better things to fix but I thought I would bring it up. An example is DUrT 4.2 LMS [UAA]
*** Edit ***
After reading the list of known bugs I think this is already addressed by:
Server - Info string length exceeded.
So if that is the same bug then never mind.
