Map generation on scenario creator bugged with tree infestation

[Worldo]

OS: Windows 10 / OpenRCT2 version: develop 9466e27

Yo! I was trying to generate a map for my own private use when I noticed that every single map generated was using Aleppo Pine Trees. This looks really ugly in any terrain aside from forest.. so I tried removing it from the objects list before generating a map... now it doesn't generate trees at all with trees toggled on! Any ideas?
