fix: dangling pointer in mission when saving character data

[EmosewaMC]

Fixes an issue where characters would lose mission progress due to a dangling pointer in mission data.
This was proven by adding a logging message to the destructor of all CD tables which revealed that when crashing, the tables and all their data are destroyed first and then character data is saved. This causes all missions to enter a state where their pointers are dangling and character data will enter an invalid state.

This is a quick patch to get character save data stable and remove the dangling pointer.

Tested that previously, I would lose my mission progress with 3 clients in world 1251 1 every time on multiple characters and after the patch I would never lose save data.

Yes there are memory usage increases. player character safety >>>>> a bit of memory savings right now.
