Seriously, I think everything here is coming to the absolutely wrong way. No matter if slide bug or gibbon, both caused that global hill records list is what at the moment it's - is unfair (and even I have that opinion, owner of offline 3 world records and 14 Polish records, and one online world record which is also my only Polish record; all jumped with gibbon). Where do you see the problem with fixing physics bugs, mostly slide bug and gibbon? If you keep them, the game won't be still as it is written by you on site:
"All your movements are simulated accurately according to real-world physics." Last time when I read this I always laugh. Sorry for that, but everyone knows what's the reason of that situation.
Anyway, you wrote "Earlier I tried to adjust the physics, so that the jumper would lose control on such moves, but it didn't work out well.". And now question: Why didn't you ask any experienced and top player to check how he feels that? All this type players for sure could help you with that. The same situation could be also with adjusting the startgates on all hills. Also, "For gibbon it's kind of too late to do anything." For everything it isn't too late! This problem is still topical and serious! And now we have another serious, maybe even a bit more serious, problem with landing slide bugs! We can't ignore that!
But, removing records and, which is the most radical way, banning players who are exploiting both physical bugs to break global hill records, is undoubtedly the worst possible way, because THE PROBLEM WILL STILL EXIST! The only way to solve it is finally make serious changes in jumping physics in-game: trying to make a gibbon should cause in the best case flying too much forward with skis with small chances to defend (in the worst case making frontflip and fall on spine), and now slide bug - trying to do slide by back of skis, when skis touch even a little bit a landing zone, jumper must immediately fall on his knees or spine. There must be keeped the word written on site, which I quote again here:
"All your movements are simulated accurately according to real-world physics." Again I bold this sentence to be visible better. Please don't avoid fixing this problem, do what will be the best for everyone playing this game. Without that, the best name for this game isn't "Deluxe Ski Jump 4", but "Deluxe Ski Bug" Why? Because of bugs like: gibbon, slide bug, landed slide bug, Bad Mitterndorf, etc.
And, also, please take a look. We are in 2018 year. And now here is bunch of information about hills.
- hill in Bad Mitterndorf was renewed in 2014 and now has HS on 235 meters
- hill in Engelberg was renewed in 2016 and now has HS on 140 meters
- hill in Oberstdorf was renewed in 2016 and now has HS on 235 meters
- hill in Planica was renewed in 2013-2014 and now has HS on 240 meters
- hill in Sapporo has new snow-profile and HS in it is 137 meters
- large hill in Zakopane was renewed in 2016-2017 and now has HS on 140 meters
- some hills should have updated hill sizes without renewing them: Garmisch-Partenkirchen (140->142), Harrachov (205->210), both Lillehammer (100->98, 138->140), both Val di Fiemme (106->104, 134->135).
Not enough that game is bugged, moreover it's outdated. It's boring to still jump on outdated hills when in real world there are renewed ones.
Don't you think that it's finally time for changes? Or we have to enjoy bugged and outdated game? Are you going to be on players' side or listless side? Please finally decide. We hope your decision will the best for everyone: for you and for all players. Thanks and warm regards (as we say in Poland "pozdrawiam cieplutko")
PS. If you still don't have plans and you don't want to develop this game please finally write on the main site "Development of DSJ series has been officially ended and it won't be launched again."
