CURRENT_INN was entirely removed from sources - it is not possible to guess.
This is required to be merged before serverdata!170 (merged)
Please read the server-data MR for info about these changes.
Note for @Micksha - With this applied, save objects must have inn field set to NO_INN
, unless it is in an Inn, then it must be set to INNNAME_INN
, like REDPLUSH_INN or RUSTYPICK_INN.
