Hi there, I received a lot of messages running up forge server and version 1.12.2 of minecraft.
All the mods I downloaded are 1.12.2 mods but IC2 is throwing these... Can someone tell me please.
2) My understanding is that minecraft has moved to a system of naming things rather than using numbers - so what are all these numbers for?
3) If it is a problem - is it something I can fix?
4) If these messages aren't really an issue - any way of getting rid of them in a valid manor that will still work syncapatiously with other mods I.E ( these errors are gone but will still report an actual error if one occurs ).
That's not IC2 producing those warnings but Forge. Essentially the other mods had shifted the IDs relative to what was previous saved, so you end up with them realigning (and logging it in the process). I don't think it's anything you can stop, but neither should it be of any concern as it is designed to do this now that IDs aren't fixed.
So if I used a save where no mods have been installed in theory i should not get those messages? or is the registration more persistent than that I.E those all entries would need to be purged from the registry and started from scratch?
If you use a new save (or one without any mods) then yes you shouldn't get those messages.
Each save has its ID mapping which is detached from the game's, so every time you load a save up with a new mod that adds blocks or items it will claim those IDs for the save. Thus if the loaded mod list changes, it can end up with the game's registry being different to the save's IDs. The reason behind this is so theoretically you can load a save without a mod and then load it again later with it without losing anything. Technically you probably could realign a save's IDs, but you wouldn't see a practical different aside from the warnings not appearing unless you'd run out of block IDs from adding too many mods.
