on the 11/15 mod update it gets rid of all already placed loaders. only fix i have been able to find is to use old mod.

Can you provide some more context? What mods are you using? Do you have a save file you can share the shows this happening?

Are you using 5 Dim's transport and were using Loaders Modernized before I added support for 5 Dim's belts?

yes i was useing 5dm's before it was added.

And the loaders that were removed - were they loaders from this mod, or were they loaders from 5Dim's mod?

just from troubleshooting I think the conflict might be between this and Ultimate Belts Space Age. I saw this -

Failed to load mods: loaders-modernized/data-updates.lua:4: attempt to index field 'express-mdrn-loader' (a nil value)
stack traceback:
loaders-modernized/data-updates.lua:4: in main chunk

but disabling that and leaving 5 Dims New Transport enabled shows no conflict.

Wait... Ultimate Belts AND 5Dim's Transport at the same time?! Yeah, that is definitely something I didn't even consider, let alone test.

I am fixing the situation where Modern Loaders were used with 5Dim's prior to 0.7.6 and then the update adding specific support for 5Dim's lost the first 3 tiers of Modern Loaders. Should have a fix out for that soon.

i havent used ultimate belts but use the loaders form this mod not the 5dm ones.

I think I may have the condition you are seeing fixed. Please test 0.7.8 and let me know. If not, I'll want to get some more detail from you on how to reproduce exactly what you're seeing.

I can confirm that that fixed it. It's back to the behavior before 0.7.7. was out, which is to say it coexists with both other mods without problem.

So uh not sure what cases were fixed or not, but I'm running UltimateBeltsSpaceAge with 5dim_transport and Loaders Modernized and when I load into game pre-0.7.6 all my loaders go poof, :D

See the information page, changelog, and settings. If you have existing 5Dim loaders, there is a setting to reenable all the loaders. As long as you didn't save the game with them gone, they should be there.

I'm using loaders from this mod for the belts from Ultimate Belts but they go poof when I update the mod :D I've downgraded for now

Can you send me your save file?

Where do you want it sent, got some discord I can add you on maybe :D ?

file.io, tempfileshare, filebin could all work. I'm on the Factorio Discord as well.
