CTI, like many other mutators, initializes the config by relying on the unreal script feature which uses default values for each data type that is not explicitly specified. For the int type (which is used to store the config version) this is zero - detecting zero allows to understand that the mutator is being used for the first time (which means it's need to generate a config). But now the game contains a bug that initializes the config values randomly if they are not explicitly set. Thus, the config may have incorrect values or not be created at all. This is why I recommend explicitly set Version=0 in the config for the first time.
[*][b]bDisableItemLimitCheck[/b]: The original game does not support more than 256 trader items, adding items above this limit causes bugs. If this problem is solved (For example, if you are using a mutator that has already fixed this problem or by enabling [b]bApplyPatch[/b]) then it can be set [b]bDisableItemLimitCheck=True[/b] to remove the limit, otherwise it is better to leave it "[b]False[/b]".
[*]Set [b]bApplyPatch=True[/b] to fix some base classes of the game: this fixes problems when adding more than 256 items to a trader and will allow players to sell weapons that have been removed from trader inventory. Note that enabling this parameter replaces the following classes: KFAutoPurchaseHelper, KFInventoryManager, KFGFxMenu_Trader, KFGFxObject_TraderItems. There may be compatibility issues with mutators that also replace them.
[*]Set [b]bPreloadContent=True[/b] to load weapon models in advance and have no lags during the game. In some cases (usually if there is a lot of custom content), enabling preload can cause models to disappear. It is recommended to test how this setting affects the game for your server configuration and then decide whether to enable preloading or not.
[*][b]ReplaceFilter[/b] - changes the trader filter allowing you to buy original DLC weapons without restrictions, unlocks future DLCs as well (no need to update this mutator). However, it replaces the - [b]KFGFxMoviePlayer_Manager[/b] class so it may not be compatible with mods that also replace it.
[*][b]ReplaceWeapons[/b] - replaces DLC weapons with their unlocked variants. Compatible with any mods, but may require a CTI update after the release of new DLC weapons.
[*][b]True[/b] or [b]Auto[/b] - selects the most appropriate option automatically. Recommend putting CTI.Mut last in the mutator load queue if you use this.
[*]Set [b]bAll=True[/b] if you want to remove all items (can be useful if you want to set the entire sale list in the [b][CTI.AddItems][/b] section yourself).
