I was trying to remember the point of the Magnet Card. I thought it was pick up items and put them straight into the ME system, but instead it items were either left on the ground or instantly sucked in my inventory. I noticed the filter button above the card slot. I added stone to the filter.
When I threw some down, it started to suck it up and then froze and crashed the game.

Also if you try to restart the game the same crash as soon as I try to load the world. I have remove the mod, reload the world, then exit and re-enable the mod and the world.

Crash Report.....

you're using the wrong WCT version for AE2 RV6..use 3.10.x versions for RV6. Also please don't paste logs in isseus. Use a service like github gist or pastebin please..also I'm completely rewriting WCT atm with a large focus on the magnet to make it better

Twitch Desktop doesn't let you know when a mod is Beta beyond the last Release.
Most devs just want the crash report however.

You can pre-load the Issue with text like what do with crash reports and to check this and that and what info you want listed in the report. Just a though.

yeah..also zero devs want the report to take up the full page..hence services like github gist

Actually there are devs that have no problem with the crash report being pasted into the Issue report.
