Hi! After upgrading to the release 2679 i get such exception during map compilation: Exception in thread "main" java.lang.AssertionError: mdr20 value changed f=293 t =295 count=357 at uk.me.parabola.imgfmt.app.mdr.Mdr5Record.setMdr20(Mdr5Record.java:129 ) at uk.me.parabola.imgfmt.app.mdr.Mdr20.buildFromStreets(Mdr20.java:116) at uk.me.parabola.imgfmt.app.mdr.MDRFile.writeSections(MDRFile.java:312) at uk.me.parabola.imgfmt.app.mdr.MDRFile.write(MDRFile.java:252) at uk.me.parabola.mkgmap.combiners.MdrBuilder.onFinishForDevice(MdrBuild er.java:382) at uk.me.parabola.mkgmap.combiners.GmapsuppBuilder.onFinish(GmapsuppBuil der.java:161) at uk.me.parabola.mkgmap.main.Main.endOptions(Main.java:560) at uk.me.parabola.mkgmap.CommandArgsReader.readArgs(CommandArgsReader.ja va:128) at uk.me.parabola.mkgmap.main.Main.main(Main.java:119) I suppose that root of the problem lays in --lower-case --code-page=1250 switches, because without them everything works fine. Thank you in advance for any help :).
