Hello I have a perplexing error, this time around after a complicated git merge, and I have had similar on one occasion a while back. I think I resolved by omitting the file, which is not really a resolution. This time I need a better solution! On compiling a thconfig I get an error: C:\Program Files (x86)\Therion\therion.exe: error -- 11-DeerPlan.th2 [8] -- invalid length reading -- -projection The start of file 11-DeerPlan.th2 is like this: encoding utf-8 ##XTHERION## xth_me_area_adjust -160.83 -127.28 965.01 763.65 ##XTHERION## xth_me_area_zoom_to 200 ##XTHERION## xth_me_image_insert {502.386220472 1 1.0} {626.342677165 11.8} ptopoDeer/11-Deer_p.xvi 0 {} scrap 11-DeerPlan-s1 -projection plan -station-names []@11 -author 2023.02.26 "B Mutton" -copyright 2023 NZSS -scale [0 0 787.4 787.4 0 0 10 10 m] point 10.25 711.5 label -text "Deer Pot" -align l -scale xl point 186.25 712.5 anchor -align r This is a well established scrap in a well established file in a well established project and both of the parent branches compiled without issue through many editing and versioning iterations. Comparison with both of the parent git branches do not suggest any changes that should trigger such an error - at least I have not found it yet. I have checked this file and all calling it for closed blocks (scrap endscrap, map endmap, centreline endcentreline, survey end survey etc) because long ago Therion used to complain in a similar manner if such blocks were not closed (reporting survey data type error due to a drawing file error - illogical). Since this is the second time in a month I've experienced this type of 'illogical' error after nothing like it for years, I'm wondering if anyone else has, or has a clue as to what might be happening?
