About the lotus bloom bug, as I reported in the android thread, sometimes auto mana will use the lotus bloom, it seems to be that it's mainly when the lotus bloom give exactly the mana needed (for example you have 2 untapped lands with nothing in your mana pool and want to cast a 5 mana spell).
This is not always consistant, I did got a few times when it didn't work but it seems reliable enough that I can at least get some use of the lotus bloom in my games.
About
Vesuva and other clone/copy abilities, if it's the same as with android, then from my tests cards that copy another (vesuva, copy artefact, clone, ...) seems to have their activated abilities linked to the original permanent instead of the copy.
This is easier to check be copying an equipement under your control, as you can see that after equipping the original on a creature, selecting the copy to equip it on a different target will move the original instead.
Strangely
Vesuva seems to be an exception and sometimes work as intented, I usually have it working when I copy a double land (the original ones like tundra/plateau and so on, the other or the lands with 3 manas don't work, probably due to triggering the original instead of the copy like for other copy effects)
