I tired removing all mods (excepted flans) and all content packs, still crashing.
It was working good months ago, i was able to play with this fleet pack but now i dont know why i am
getting this issue.

Please help me, i searched for hours and hours how to fix this but never found a good way.
Thanks.

I'e found a way to make it work, after 2 hours of sesrch. Open Fleet Pack folder and remove all .DS_Store files, i did this and now its working fine, remove from vehicle folder, assets, ect.. all.

Tell me if it work 💃

I have the same exact problem. ;-;

You think it has to do something with Forge? I downloaded the latest Forge, so maybe I will downgrade and use the Recommended Forge. Imma try that and come back here if it works or not!

Could be a content pack problem. Make sure you have all the part packs especially mecha parts pack - this one can cause problems on vehicle placement if you don't have it.

I have all the simple parts and smp parts content packs. It still crashes me ;-;

Seems this is likely a content pack problem. Are you able to replicate this issue in the latest Flan's mod version (5.1) and a official content pack?

Ok, it seems that all the JamioFlan packs work. I will now try each pack individually to see if they work and then find which one is causing the problem. I will not be able to try out the Manus packs being the SMP site is down.

Ok, so it seems every content pack worked EXCEPT the Fleet Pack. Lol, the one that Creeper was having trouble with before. I will be deleting the .DS_store to see if that works, but if it doesn't I will delete the pack all together.

Ok, so deleting the .DS_store folder did not fix the crash problem, so I will be deleting the Fleet PAck all together. Thanks for the help!
