The CPW coming out of retirement edition.
We added a lot of logging in this version. The debug version of 4.2.3 is standard when you are in edit mode.
We implemented checks for non-existing mods and made it so that those items get deleted and replaced by a new Invalid Item ( new item of hqm, does nothing ).
A special logging system for when you have edit mode enabled.
Everything is done in the logs. For end users it's not really useful, but for quest writers it is.
On load it will log all quests, rewards and reward bags. If ANYTHING goes wrong, the logs will let you know. What items went missing, and if they got substituted for the invalid item.
