PAPPY,
Unexpected txr reload errors are not critical.
The error message,
Allowed body types are:WoodSmall,WoodMiddle,RockMiddle,RockBig,RockHuge,FuelSmall,FuelBig,Flesh
is appropriate to v1.5. The v1.6 message would read,
Allowed body types are:WoodSmall,WoodMiddle,RockMiddle,RockBig,RockHuge,FuelSmall,FuelBig,Flesh,Vehicle
Note the addition of the new body type, Vehicle.
In my haste to correct this, I'm assuming that indeed the error is mine, and not that you've not somehow got the older v1.5 version of the 3 House.class classfiles present in your install. That is, I didn't decompile the classfiles included in my v1.6 mod archive mod in order to see if the code was indeed the older version, jumping straight away to supplying the 3 classfiles from my own working install.
Update #4 in the top post provides a link to the 3 correct classfiles, to overwrite those present in the main effects folder. A readme file is, of course, included.
I've also updated the full mod archive.
If this does not address the issue, it won't hurt anything to use these classfiles; they are current.
