Test Map on Older WC3 Client

[Wark]

Can anyone check if this map:
Northrend Bound v1.77
works on version 1.27 or 1.28 of WC3?
I am trying to make it compatible to any client for v1.27 up, and I don't have an older client.

Hello Wark, I just tested on my 1.27 wc3, and unfortunately, I was taken back to the screen.

Ah, thank you for letting me know. I'll have to figure out what I missed
