A word from Smoth.

[oksnoop2]

Smoth messaged me out of the blue and told me to warn people on the boards.

If you want to skip the read basically he wants to warn people that with a gamespawn gadget like this:

http://pastebin.com/60pHtEE4


The start unit will not appear on maps with units on them, like Gunmetal harbor.

He goes on to say to remedy the situation delete:

Code: Select all

        -- only activate if engine didn't already spawn units (compatibility)
        if (#Spring.GetAllUnits() > 0) then
                return
        end

Or use:

Code: Select all
