Due to testing of our new currency system Gloebit, if you do not want your items to be sold for free, we recommend disabling your vendors for the week 4 to 5 days. Also shop owners that have there own vendors systems you can test this system as it is in sandbox mode. sign up at http://www.sandbox.gloebit.com/
Once testing is finished a grid wide roll out will follow. Gloebit is replacing OMC as our currency and the module will be included with our regions as a stadard.
