Post your working bug here and explain how you do it !

Float HT or DT !
I have no idea why they didnt fix it when they patched to 1.10 !
Now for how to do it.

Click = Where you want them to float.
S = Hotkey for stop.

Put them at a good distance.

Send the merge command then shift+*Click* and right before they merge press *s* key.

If you did it correctly they will float !
its an easy way to enter terran base.
