So I keep getting an error when I play certain maps in Halo custom edition, custom maps. The game minimizes and a small box appears with the text "Gathering exception data..." and then it says Halo stopped working and blablabla a problem caused it to stop working and I the minimzed halo closes. I've noticed that this error only happens when I download and play more demanding maps which have been heavily modded such as lumoria and flood:the forgotten exile, the only exception being cmt spv3 truth a reconciliation (It could work though because it is a campaign custom map). Whilst other maps which are pretty simple and don't demand much such as h3 foundry and grunt attack can easily run without no issues. I've looked up how to fix this issue but so far none have worked, i've tried various fixes. Can someone help me? This is a forum with lots of avid Halo CE players so I hope some of you can help me resolve my issue. Please. Keep in mind this error only occurs when I play certain heavily demanding and modded maps. Unlike others who have this error occur when playing multiplayer.
