Decoration Platforms in Guild Hall Not Compatible With Some Skills and AI

[Overedge.2435]

The recent update to guild halls that allow you to change your character's stats to those from different game modes has really revitalized the excitement of a lot of the members of my guild, as most of them are duelers/roamers at heart. Before the February 2020 competitive split we spent a ton of time dueling in the guild hall, and not being able to access WvW balance there had become a real bummer.

So I celebrated the update by going into the guild hall and going a little crazy with the decorating. I crafted a ton of those holographic racing platforms to build more fighting areas with, but while testing things out, we discovered that any skills that pathfind -- such as Shadowstep and Blink -- do not work on the platforms. I'm guessing that the pieces aren't navmeshed properly, because anything that uses AI, like illusions and pets and minis, also don't function properly.

Additionally, with the Holographic Track pieces (the glowing green ones), some abilities (like certain wells and necro marks) are invisible when placed on the platforms.

Would it be possible for ANet to go in and add navmeshing to decoration pieces?

Some classes are far more affected than others. We've started putting together a Fight Club based in our guild hall (open to players from all servers, though we're on NA so EU likely can't access it) so we'd love to be able to do some really interesting things with the terrain.

I have no doubt that it would be a huge undertaking, but if enough people and guilds were interested in taking advantage of the guild hall updates, maybe it will be worth it. Here's an extensive but likely not-quite-exhaustive list of affected skills. If anyone else decides to test this and finds more, please contribute to the thread.

While doing some more exploring of the Isle of Reflection during our first night of Fight Club, we discovered a few more locations on the Isle of Reflection itself that also seemed to be missing navmeshing, and we experienced the same "no valid path" errors there, and decided to map them out to add to this post. Here is an image of the locations we found on our first major run-through, and we'll continue to search for more. For the buildings indicated, it's the rooftops specifically where the errors occur.

Clarifying some information

I thought it would be fun to try to build an arena today (with racetrack and other platforms) to try the new weapons. When I was done I tried my necro wurm and discovered it too. Such a shame 😞 

[kapenike.6793]

Yeah 😕 it's an issue in WvW too ... seems to be a development issue that no one wants to tackle. Could be pretty tricky with dynamic terrain but with the new guild hall update I foresee a bunch of complaints ... like from me! I put so much effort into my arena and combat areas and it's not even worth fighting in. So sad
