Strange Error

I just got this error...I dont know how to fix it:



the Unit is by Wyrmshadow:
Modern Worker

the error in question, seems to be refering to the speed...but Ive never seen files for them...maybe the INI is set-up wrong???

[edit] also note, there are a few other errors in the INI for this unit...the death and run are misnamed...

look in the release thread for my posts. i think i had a similar error, because the ini was screwed up

EDIT found it

Aha...great...thanks...

Im in the middle of a good game and dont want to lose it...but how did you fix it?...I had already rewritten the INI...

for the record, does anyone know why this happened?...so I can fix it in the future...

i just took the modern worker ini from PTW as template if i remember correctly.
