@chonkie @SeniaX tryout this mod from @tanuki , see if it works and loads the ymaps https://www.gta5-mods.com/tools/ymap-load-list-extent-limit-fix-fwboxstreamervariable-patch

Nice. Thanks for the solution.
I actually missed the meta rpf resulting in disappearance of ydr and allowing loading of the ybns but soon corrected it .Below is for the mod GTA Belgium Las Ventura's - Remastered, But I suppose it will work for the other version as well. Posting it in-case someone comes looking

@chonkie Hi, I wasn't able to solve it, but got partially resolved by doing my own rpf with a help of a template, its was simpler. But I never was able to get both phase working. Anyhow, I lost all my apocalyptic ymaps so didn't try again that approach. Though I do remember for my custom maps if any ymap collides with another then I think one the ymap wont load up. Also too many props to load when I was trying to load up with custom_maps folder size exceeding 700-900kb or maybe Mbs. I also didn't setup any lod like JRod, Larcius or many other custom add-on map makers.

Hopefully @SeniaX is just facing a ymap colliding issue.

@alebal contact me via msg or add me in discord Yogesh#4013 . Will go through everything easily.

@alebal Hi, I found one with google search. Instead of replacing in-game vehicle, install a addon mod boat mod and replace the files by renaming the yatch in add-on vehicle name and edit the handling. I spawned and worked just fine. Try it once

@alebal google the same u will find it on the internet.

@maxcsw I don't think there is a option for stop logging that I know of but maybe there's a conflict of some mod I think. Though the crashing is weird.

@maxcsw maybe delete the log if u think that's the root cause But try check for error mentioned in the logs first, Both openniv and scripthook. Check for adjustor file and gamconfig. Try loading game without reshade and redux. Check for any conflicting mod.

@alebal can provide the link to which vehicle mod you are referring to ?
