Good catch! hpmult indeed breaks terraform.

Terraform gadget is a mess. I'd place my bet on this string:

quote: local terraUnitHP = 1000000 --hp of terraunit, must be the same as on unitdef

Clearly it's no longer equal to 1000000 after you applied hpmult in unitdefs_post

quote: local terraUnitHP = 1000000 --hp of terraunit, must be the same as on unitdef

Why isn't this

quote: local terraUnitHP = UnitDefNames["terraunit"].health

Another fix:

quote: for id,data in pairs(UnitDefs) do if data.name ~= "terraunit" then data.health = data.health*hpmult end end

Or something like that. Very simple fix, probably. If UnitDefs is an ordered table, you can just do:

[quote]for i=1,#UnitDefs do
if UnitDefs[i].name ~= "terraunit" then
UnitDefs[i].health = UnitDefs[i].health * hpmult
end
end[/quote]

Disclaimer: I am not totally knowledgable in this subject, take this as an amateur's opinion

Its wasn't true terraform. BB could shoot throught it and units cross it. Its like graphical glitch.

that is one ugly screenshot!
