Attached is a little mod that adds keyboard visualization of hotkeys including testing capability on your configured keyboard for both 0AD releae 0.28 and the SVn version 0.,29. It will be also available from mod.io once signed. show-keybindings-r28.zip show-keybindings-maintainer.md show-keybindings-r29.zip

It's the same as the cougar, puma concolor in binomial nomenclature  

Don't forget the second big cat of Sudamérica after the jaguar! (although present in North, Center and South America): The Puma, a.k.a. the Mountain Lion

Limiting the amount of repairs seems like a complicated rule. All this was just to justify a Tachunautousa Triērēs as a champion trireme for the Athenians, and maybe redefine the Helepolis as a champion siege tower. For both, garrison prohibition (and high population cost) would work, making them "fully garrisoned" always (although for the Helepolis, eventually units should be able to go through it to take walls, just not be able to stay inside to change its stats). I guess the only problem is catapults, a solution being adding at least one garrison place for them. This is not far-fetched, since catapult operators are always at least two, and I remember catapult crews up to 9 and 11 people for Greek and Romans, respectively. High population cost should be properly balanced to avoid any super siege domination.

@Atrik You are right, should 've opened a bug report officially. My point was, however, that I was not sure it really is a bug or if I tampered with my install too much. Thatt's why I asked for other observations. Thanks that you fixed it!!! Got to learn how to open git tickets, shouldn't be too difficult .
