The initial version of the mod for TFH is now available for download in the downloads section. Install instructions are underneath the download summary and provided in the readme. Please note that where you need to place the mod's files has changed! Don't place the files in /hoi3/mod; place them in /hoi3/tfh/mod instead! Please note that combined arms and armor/pen. is NOT implemented and that the AI will need some work. The mod likely will have bugs, so this version is mostly for testing.
If you download the mod and find any stability problems, then PLEASE report what you were doing before the crash. Simply saying "I'm getting a crash" won't help me solve the problem. Likewise, if the AI seems to fall asleep (could be possible due to AI mission changes between expansions), I need a copy of your system log file. This file will be located in \Documents\Paradox Interactive\Hearts of Iron 3\HPP\logs and is named system.log. This is the file where AI errors are reported, so I need it in order to debug the AI. You can send files to email@example.com or post the errors at the bottom of it here in a comment or in the mod's ParadoxPlaza forum.
Also, Custom Game Mod does NOT work with the mod's tech system. Feel free to use it to adjust your position on the diplomacy screen or neutrality, or use it to reorganize your OOB, but you won't be able to adjust your starting techs.
