Purple Trees in certain parts of campaign map

[SonOfOdin]

Well yeah, I have some purple trees in the campaign map
From what I can remember, they are located at : Modern day Croatia, A little bit north of Macedonia, Northern Germania, some parts of Gaul

I will provide screenshots later today

Any help please?
Note : I have Roma Surrectum installed but since both EB and RS are mod-foldered, I don't think they interfere with each other

Though it is peferable that no other Mods be placed with EB (for stability reasons) I dont think it would cause purple trees, for that I beleive you might need to upgrade your video card.

Upgrade my video card for RTW????
I play ETW on medium you know...
