Entangle Goldmine upgrade to shorten the building time?

[Blahblah_Blagar]

Any ideas how to do this, considering the Entangle Goldmine ability glitches a lot in the editor?

Making a trigger hiding this ability and replacing it with a better one doesn't work as this ability cannot be hidden. Making it a 2 level ability doesn't work, as it doesn't acknowledge the upgraded stats. Berserk upgrade doesn't work, as it either glitches the Tree of Life (if you berserk it) or doesn't seem to replace the goldmine til it's already build. Spellbook shouldn't work, as having both of these spells at the time glitches it (it always uses only the original version)

Any ideas?

Did it. While the upgrades can't change the level of such unique ability, the triggers can
