 - Please stick to the issue template, it's there to help you provide the right information so I can fix the problem more easily. If you're not sure what to put for anything, that's ok, just leave it as it is.
 
+- One issue per issue please! Make a separate issue for each bug/suggestion. If you think multiple different issues may be related, reference between them using # followed by the issue number.
+
 - Please give me as much information about the issue as you can, but keep it relevant. "This is really annoying me and my friend" does not help me fix the problem!
 
+- Make sure your wizardry and Forge versions are both up-to-date for the game version you are using.
+
 - There's no need to put 'tags' in square brackets in the issue title, I'll put proper github issue tags on it which will also help organise it. You can use them to search for issues too!
 
 - Don't close an issue unless it has actually been fixed or is no longer relevant - otherwise I might not end up fixing it at all! Usually I'll take care of closing issues anyway, so you don't have to worry about it.

 Source code for Electroblob's Wizardry, a Minecraft mod currently for versions 1.7.10, 1.10.2, 1.11.2, and 1.12.2. Wizardry adds an RPG-style system of magic spells to Minecraft with the aim of being as playable as possible. No crazy constructs, no perk trees, no complex recipes - simply find spell books, cast spells, and master the arcane!
