Adjacent tracker arrays at a nonzero azimuth giving error

[dtarin]

Hello,

I have two tracker arrays shown in attached image one, where the length of rows is different for the two blocks. If they are set to zero azimuth and placed adjacent to one another (with the spacing shown in image 1), there are no errors. If I change the azimuth to say 12 degrees (image 1), I get the error message shown in image two. The two arrays are separated by >5m. Is there a bug which arises when the azimuth is changed? The arrays need to be separated by more than 11.12 meters for the error message to go away. PVsyst version 6.63.

Thanks.
