This applies for Quick Inventory v4.02, Better Radial Menu v4.02 and Friendly HUD v0.9.4NGE.

Since v4.02, both Quick Inventory and Better Radial Menu mods modify the hudModuleQuests.ws and hudModuleMinimap2.ws scripts, which are also
changed by Friendly HUD. And merging is not easy.

If, after using Script Merger, you get compilation errors about currentlyFading, isFading or fadeInTimer, like:

Error [mod0000_mergedfiles]game\gui\hud\modules\hudmoduleminimap2.ws(177): I dont know any 'currentlyFading'
Error [mod0000_mergedfiles]game\gui\hud\modules\hudmoduleminimap2.ws(179): I dont know any 'currentlyFading'
Error [mod0000_mergedfiles]game\gui\hud\modules\hudmoduleminimap2.ws(180): I dont know any 'isFading'
Error [mod0000_mergedfiles]game\gui\hud\modules\hudmoduleminimap2.ws(181): I dont know any 'fadeInTimer'
Error [mod0000_mergedfiles]game\gui\hud\modules\hudmodulequests.ws(87): I dont know any 'currentlyFading'
Error [mod0000_mergedfiles]game\gui\hud\modules\hudmodulequests.ws(89): I dont know any 'currentlyFading'
Error [mod0000_mergedfiles]game\gui\hud\modules\hudmodulequests.ws(90): I dont know any 'isFading'
Error [mod0000_mergedfiles]game\gui\hud\modules\hudmodulequests.ws(91): I dont know any 'fadeInTimer'

then the easiest solution is to remove these two script files from Quick Inventory and Better Radial Menu and then run Script Merger again. There's no hard dependency to them and the game should be able to compile the remaining scripts without errors, as long as there are no other issues. Obviously this means that Quick Inventory and Better Radial Menu mods won't be able to change the visibility for the Quests and Minimap HUD modules. In other words, the Show Minimap When Open and Show Current Objectives When Open options won't work.

The paths to the script files:

1. mods\modBetterRadialMenu\content\scripts\game\gui\hud\modules\hudModuleQuests.ws
2. mods\modBetterRadialMenu\content\scripts\game\gui\hud\modules\hudModuleMinimap2.ws
3. mods\modQuickInventory\content\scripts\game\gui\hud\modules\hudModuleQuests.ws
4. mods\modQuickInventory\content\scripts\game\gui\hud\modules\hudModuleMinimap2.ws

Do not delete the vanilla script files located in content\content0\scripts!

Another possible solution is to keep the files, but don't merge them, so they must be listed as a conflict in Script Merger. Then set the priority for Friendly HUD to be higher than Quick Inventory and Better Radial Menu mods, so the game will load the scripts from Friendly HUD. Is safer to delete them though...
