getting a huge stack trace report whenever anyone on my server tries to command a mob to do anything. Every command gives this error and it spams the console hard. This has been happening for a few weeks now with several different dev builds.
I am on the latest RB with the dev build 46 of MobRider. Plz Fix.. as i have an entire rank based around this plugin.

Can you send me the version of bukkit you're using? I just tried it out on 1.2.4-R1.0 without those issues.

again... I am using the latest reccomended build for 1.2.4 -R1.0
command : /mob goto 0 0

Wow.. so I guess this plugin is now Dead! 2 Months and no responce, or even an attempt at fixing the issue.... Another one bites the Dust!

Not quite yet :) Just haven't had spare time recently.

how soon can we expect a new build for this?

Been well over a week. Have you located the cause of this issue yet?

...... almost a full month since the last dev build... man I'd really hate to see this plugin just die. such a shame.
