As you may know the Flans Mod adds vehicles, guns, armor, And more into the game. So like I was told I downloaded some Content Packs. I Tried Placing one vehicle and it crashed my minecraft. I Have tried multiple times but it still crashes. Im also having problems with the Instant Structures Mod. [Both run Forge] [minecraft version 1.7.2] I don't know if its my computer [HP ENVY dv6 Notebook PC] Or Minecraft Itself. Or In a rare Case The Mod. This Is What it Said The Last Time...

Not seeing much of a problem here, did you install the content packs correctly?

Content packs are meant to go in /.minecraft/Flan/
