So I downloaded the 099 Core that was provided here. And I used the SVN to download the current Distro. I had to make some of the (what appear to be) usual changes in regards to 0x1FF0 and it's brother, and the wrestling item number. Etc.. Etc... I'm at the point where everything compiles. With my client (Installed Mondain's Legacy, same version that was used in Edwards Zulu/Fantasia servers, with the same Zulu release files (.muls, etc..). I get to where it's going to create my character and then it does this on the server console;

[02/17 23:43:10] Client#3: Exception in i/o thread: Assertion Failed: equippable( item ) (It is impossible to equip Item with ObjType 0xe75), mobile\charactr.cpp, line 1617! (checkpoint=4)
[02/17 23:43:10] Client#3 (192.168.69.1): disconnected (account admin)

0xE75 is the backpack, specifically;
The client gets hung out to dry. Doesn't crash the client, just sit's there doing "Creating Account..". I looked at I've gone and modified the starting locations as well, thinking maybe that was the problem, but alas, no victory.

I'm also seeing lots of these types of errors in the logs as well;

Not just the onLogin hook;

Can't find executor.cpp so I can't find why line 269 cause's all these packages to throw errors. Lead's me to believe it's internal to the UO client.

Any assistance greatly appreciated... I'm looking forward to the launch of our new project!

I'm having the same errors. Can anyone shed some light over this?

I'm not familiar with the 099 distro, but...

1) Make sure that you ran uoconvert to get the tile information, *maybe* the backpack is getting the wrong tile

2) The .em files in the modules/ folder should be the same version as the pol.exe you got. Move them there and recompile all scripts. This looks like scripts that were compiled with the wrong number of parameters.

You just need to turn off Assertions.
Normally it comes set to 1 in the POL99 Distro.

I discovered this later today.

Assertions mean that something is wrong. If you turn them off, you're just masking the effects but not solving the problem.

I posted a bug report on this.

After I turned on Assertions the only difference was that the server didn't crash. The problem remains the same. I was able to trace it to a core function from the basic module, SplitWords().

This was solved by placing an "include/packets" in the season system.
