  3. If there's no mention of Forge or a mod, but any Vanilla class, you might have found a Vanilla bug. You should probably still report it via the Forge channels first, however, due the nature of modded environments and the rarity of Vanilla crash bugs.
  4. Always check whether there's a mention of coremods at the beginning of a crash report. If there is and you can't find any clear culprit, consider reporting to these coremods first, since they are free to change any of the code executed in your environment.

 ### Preventing Duplicates and Unnecessary Reports
 Use the target issue tracker's search functionality to look for issues which have descriptions similar to yours, but make sure to also search for already closed issues. If you can find one, verify it is in fact the same (or a very similar issue) and simply comment on it if you have anything else to contribute to the discussion, such as other steps to reproduce it. *Do not create duplicates of an existing issue, since it only puts extra effort on maintainers to recognize and close/mark them.*
 
-Additionally, always check the *latest* changelogs of Forge and participating mods to find out if the bug was already noticed and fixed by the developer. Often the maintainer may only support newer versions of the game, so also check the changelogs for versions of Minecraft you don't actually actively play. If the issue was adressed already, *do not report it*, even if the fix only exists for a newer version of the game, since the developer probably had a good reason to do so. If your issue only exists with versions of a mod that are for very old versions of the game, also refrain from reporting them, considering most modders only support the two latest versions of Minecraft, if at all.

 Every project has a different way of dealing with issues, so don't wonder if there's no comment on it, but somebody "labels" it with certain markers. This helps developers to more easily keep track of bugs and priorities. When any further input from you is required, you will be asked specifically. Do not bug anyone through other channels about resolving your issue.
