There is a bug in the "Extended Original Game" mode.
When the "Colonist" unit uses the Teleport function from a Starport (even if I built several Starports in both worlds), the game shows the message below:

This works normally for any other units I've used.
I'm surprised no one has reported this issue so far.
For that case, I found a solution in the Rules.txt file (C:\Program Files\Microprose\Test of Time\ExtendedOriginal\Rules.txt).
For some reason, the Colonist's rule is different from the Settlers and Enginners.
Settlers / Enginners rule (line 943 and 944):
11111111, 00000000, 0, 0000000000000000, 0000000000000001, 0000000000000000, 00000000 ;Settlers
11111111, 00000000, 0, 0000000000000000, 0000000000000001, 0000000000000000, 00000000 ;Engineers
Colonist rule (line 995):
01111110, 00000010, 0, 0000000000000001, 0000000000000011, 0000000000000000, 00100000 ;Colonist
Changing the Colonist's binary numbers to the same as Settlers and Engineers fixes the problem.
I tested it and it works, the message does not appear and I can teleport normally.
If you change it like that colonist can no longer transform terrain...
