Batch job keeps retrieving old code

Hi,

i've got a scheduled batch (RunBaseBatch Class) which calls a method in another Class (MyClass)

Class "MyClass" needed a fix in its code.

Now the scheduled batch seems to keep finding the old version of "MyClass".

Is there any workaround for this issue? (I mean, except rescheduling the RunBaseBatch job...)

Thank you in advance

regards
