I can see my HL LEMON TREES !
LOL you said weeks
Mine been invisible since December 23rd when I returned to the game.
bout to load up now, hope mine is fixed as well!! I'd really like another H.Lemon grove, but I resisted putting it in due to the bug (don't want to look at seemingly empty groves if I can avoid it)
edit: I can see mine too!! Woohoo!!
