using Cantor Pairing Function.● Add boost_score to rank-boost-map of client

generals.● PlayerGeneralInventory refactored when

(troubleshooting, feature implementation, moral support).

Other tasks (Not War Room)● Port features from HC2 to HC1: Guild auto-

● Safeguard pruning script (in development).● PlayerBuilding - In Progress.

Bug Fixes● Fixed unnecessary or unexpected event

queue invocations (or it’s lack thereof) in the server code from PlayerBuilding.
