Hi Jiewen, I agree with your proposal and implemented the changes you proposed here: kuqin12/mu_basecore at personal/kuqin/var_check (github.com) ( https://github.com/kuqin12/mu_basecore/tree/personal/kuqin/var_check ). Could you please take a look? Both traditional and standalone instances are tested on our platforms internally, which rendered no issues on compilability or functionality. Regards, Kun
