So... I'm a bit late on the help wagon here since the update that killed the rafts was ages ago... but i'm gonna throw you all some codes for your .ini files that will help.

First... let's get rid of the dingy... it's the server crasher.... you're gonna jumpe to your game.ini and enter the following code: OverrideNamedEngramEntries=(EngramClassName="EngramEntry_DingyRaft_C",EngramHidden=True,EngramPointsCost=10,EngramLevelRequirement=150,RemoveEngramPreReq=False)

This will remove the dingy engram from the server so no one can learn it and crash your stuff.

Again in your game.ini you are also going to want to throw this code in:

bAllowPlatformSaddleMultiFloors=True

and

bDisableStructurePlacementCollision=True

The platform saddle multifloors is the nerf to the platform saddles/rafts that prevents you from extending your platforms/rafts out too far. essentially what causes you from only being able to go about 2 to 3 foundations out instead of further.

the structure placements collisions is if you run S+ with it (recommended anyway) to allow the thatch ceiling and foundation extension trick.

Enjoy your fixes. and have fun with this mod again.
