Start with t3 hall possible?

Ok so basically I have 3 bases and I want each to start off with a t3 hall. The first method I tried disabling the melee script of creating starting units and I just created them in map editor. However you cannot create an entagled gold mine and so elf had nothing. So I tried other method of changing the tech equivalency to Castle as Tier 1. However it still created a townhall first and I figured there would be many bugs with that solution even if I found one. Any suggestions??

You could easily trigger that elf problem you had if you wanted to. Or, if you don't like triggers, just edit the t1 base of all the races to be t3, giving it all the required upgradeables and alllow all buildings to require t1 instead of t3.

You can creat a entangled goldmine. Every unit has a boolean option named "placeable in worldedit" or something like that. Change that to true and it will show up under nightelfes cathegory.
