I have run into compiler errors on several airport projects. Not from the start (the firs compilations) but after a couple. After a number of such experiences I anticipated that those compiler errors were caused by adjustments of runways with lights and lengts and widths. Later on I suspect that along with some changes made by us Alpha users it is the faulty taxisigns from default MSFS that have to be corrected or at least adjusted somewhat. A number of taxisigns have red runway info signs only. The fault finder of ADE F20 lists them. I either changed some spaces between border and lettering, or moved the black/yellow position letters to the left in the sign. After that the compilations were successful, also with changed runway specifications.
