Today while my players were working on server, we had a massive lag spike. When I checked the logs, I found this: "[16:17:49] [Worker-Main-13/WARN] [ModernFix/]: The namespace repurposed_structures contains an outdated structure file, which can cause worldgen lag. Please view debug.log for the full filename, determine which mod provides the structure, and report to the mod/datapack author, including the debug log."

Checking in the debug log - I found: "

The error asks I notify you, so I am trying to do so. Working on finding a way to give you a copy of the debug log.

Thank you for all the work you do on your mod or mods, as a player and a server owner - I see developer's efforts and what they go through and how thankless it can appear. I know my team and I all really enjoy the work all of you do.

Basically this issue report: #284

To summarize, the mansion nbt is not lagging the game. You should use Spark or something to profile the game to find the true cause of lagspikes. The mansion pieces aren't that crazy large so DFU can get through it very quickly. It's more that giant massive pieces like 48x48x48 that are many versions old that cause cause DFU to take some time but for RS, I have been testing and have not seen any noticeable lag at all with my pieces, even when using outdated nbt in 1.18.2. (Also I no longer support 1.18.2 btw)

The server's log literally asked me to bring this to your attention. I am sorry to have bothered you with this issue as I was unaware you were no longer supporting this version of minecraft. I will most likely remove this mod for now. Thank you for your prompt response.

@AeternaVigilate No need to be sorry. Just informing you of this! That modernfix logging has caused me quite a bit of reports despite no actual issue. They did reduced their logging in later mc versions.
