    @Pandemic not sure what is causing this, but just started getting it after one of the recent DB updates.  doesnt seem to affect anything but thought I would let you know

    Your script is using a class that doesn't exist or can't be found

    org.apache.logging.log4j.spi.ExtendedLoggerWrapper

    Either you are trying to use a library or something off a dreambot client lib? Check your imports if not

    script is on the SDN and runs fine there, so its not an import issue.  they added extra logging in one of the recent updates, wondering if that has something to do with it

    This is a harmless (usually) error caused by not cleaning/rebuilding your local script against the latest client build. AFAIK it shouldn't cause any problems, though.

    hmm weird, i am building against client.jar in the dreambot folder and it is up to date.  could it be related to me using java 11 (to run the client, not build the scripts)?

    I don't think so, but you can try it. Make sure you clean your project so it's actually recompiling the whole script when building.

    i invalidated the caches in intellij, deleted the jar and rebuilt - same error.  also tried on java 8 runtime and same error.  its not causing issues so not a big deal but who knows lol

    Are you definitely building against client-3.0.0.jar not client.jar?

    wouldn't client.jar be the most up to date version to build against since the launcher downloads the latest jar?

    If you have the latest launcher version (released with DB3 originally) client.jar is the proper JAR.
