EXPBG Compat - RHS

0.1.1

- Call-in support settings (RHS CISS): the attribute guard restates RHS's class attribute
  `[BaseContainerProps(), SCR_BaseEditorAttributeCustomTitle()]` on its modded
  `RHS_SupportCallInsBaseEditorAttribute`. Without it the config loader rejected the class
  (`Unknown class 'RHS_SupportCallInsBaseEditorAttribute'`, 8 per `Edit.conf` load on server and
  client in the 2026-10-14 full-modset test) and dropped all eight RHS call-in support rows, so
  they were missing from the Game Master attributes dialog and from Game Master saves, and the
  save/restore half of the -1 guard never ran. The rows, their saving and the guard work again.
