With DyTech-Warfare 1.9.9 is not possible to load game with DyTech-Warfare 1.1.0
When i will load it follow message come:

Error
item battery saved as tyoe item, but now it is type ammo

Please fix it
Thanks

hm... not sure how to fix this properly (with a migration) but I found that extracting the save and editing level.dat and level-init.dat (in notepad++) so that the word "item" in front of "battery" (there are some non-printable character inbetween) is instead "ammo" and then rezipping the save did the trick. If anyone else decides to try that MAKE A BACKUP, my test was on a fresh save with 1.1.0 and then I changed the mod out for the newer ammo version, it seemed to work, but I offer no guarantee that it couldn't somehow possibly maybe corrupt your save. No harm in trying it though, IF you make a backup first, or better make a copy of the save and test it on the copy.

Attempted the 'proper' way below (a new .json file in migrations folder) but it didn't work...
{ "item": [ ["battery", "battery"] ] }

I try to fix the other problem an change the DyTech-Tools 2.0.0 back to 1.0.1 and then i get the same error message like in the old files and the old file work!
Error
item battery saved as tyoe item, but now it is type ammo
So i think the problem is not DyTech-Warfare 1.9.9 ... it is DyTech-Tools 2.0.0
Sorry that i choose the wrong file ...

hm, yeah I got a bad allocation when I tried editing your save, and I have a feeling that Factorio's migration system isn't going to allow changing the type of prototypes (it's mostly meant for name changes...).

I imagine a simple recipe could be added to convert item batteries to ammo batteries, or Dysoch could just make people start a new game....

i made a warning that using Warfare 1.9.9 will corrupt your save, and should start a new game. Also making a bug report for it so the devs can fix it xD

[windwind12]

Try if it was Warfare or Tools and write than the warning ...

no longer needed since the ammo for the laser gun is no longer the battery, but an own item. This issue will never happen again
