I have seen the addon MERRIL C. MEIGS FIELD (KCGX) (both the freeware version and the payware version) – have issues with the new Asobo Meigs –
( or strictly, as the Asobo one came later, so the Asobo one conflict with the Addon versions )
– in that they both render at the sane time, so you can get , for example, the two Airport Buildings render at the same time, and they are not an exact fit on each other, or an exact placement.
Personally, I prefer, and want to support the developer of the Payware version of MERRIL C. MEIGS FIELD (KCGX) addon, so I have uninstalled the Asobo Megs, and now have no issues.
Even the Freeware version of MERRIL C. MEIGS FIELD (KCGX) is far more detailed, even the Asobo one, and the Payware one adds a lot more details, including airport buildings internals.
