I'm using now 6.0.14.3 on my ultima server, but it is completely unstable. There is a lot of internal crashes, for example: frequently crashing after trade window was closed, etc...

Which client do you use? I'm looking for stable version, older than 6th, i think

Maybe it's unstable due to packet changes you are missing?
That's often the only reason of client crashes.

Attach SpyUO and look what packet were last received and investigate.

As for packets, , as for changes, not all are listed there...

Best way, to see what packet was last received before client have crashed, and than looks for this packet in particular. Both in packet guide and server side handling.
