Custom Ability Hotkey bug?

My game used new hotkeys for several abilities (by editing and importing AbilityStrings.txt into the map) as some heroes have abilities with same hotkey. e.g. holy lighT and mass Teleport are both "T", so I changed holy light hotkey to "L". However, recently someone pointed out that although holy light hotkey is "L" at level 1, but when it is upgraded to level 2 and 3, the hotkey changes back to "T" spontaneously.

I found this also happens to new hotkey of other abilities. Anyone experienced similar problem? Any solution to it? Of course I can use "T" for holy light and "L" for teleport, but some heroes have two level 3 abilities using the same hotkey.

Thanks in advance!

Hmm... im not sure why it does that. Did you change the research hotkey too? Im really not sure about this one, since ive never had this problem. try doing a T,T,T that way it reads a different hotkey for every level. That may not work unless its in the war3patch.mpq archive, so im not sure how it would work on bnet.

I changed the research hotkeys already and they work fine at all level.

Another thing is that I used CommonAbilityStrings.txt instead of HumanAbilityStrings.txt, etc. Would this cause the problem?

Changing "Hotkey=L" to "Hotkey=L,L,L" works! Thanks again!
