I made a new world 1.9 I then downloaded forge 1.8-forge1.8-11.14.4.1563 worked fine downloaded mods custom npcs, Additional Blocks, World Edit and then i downloaded Thaumcraft it worked fine. However to day i experienced a crash. I've tried many hours to fix this crash. Minecraft starts up and configures the mods but when analysing Thaumcraft it crashes and displays a report: If you want me to show any more info to find the answer just ask.

---- Minecraft Crash Report ----

WARNING: coremods are present:
