Is your feature request related to a problem? Please describe.
The plugin disables saving while there exists a Game_Character with an active target following strategy, as to avoid serialization issues. Since RPG Maker MZ uses some weird kind of JSON serialization magic thingy to save game state, it's hard to make the path following strategy serializable.
Describe the solution you'd like
Some kind of specialized implementation of strategy to follow events/player/points to use with Game_Character.
Describe alternatives you've considered
Possibly isolate the path/target following system from the Game_Character class, with an implementation more akin to an ECS system.
