found a big bug today. for the past couple of days we could not figure why our server went down so much and this last time there = wasn't anyone on to reboot it so i went into single player and started messing around and re-building my base (Under water with MFFS) after i experienced the same crashes i started to narrow down what was causing it. when you have a forcefield underwater and have wrathlamps in it (from factorization) and turn off the field (only tested with the tool in switch mode) it will indefinitely freeze the game and you will not be able to open any inventories or interact with the world. i have tried to repeat this above ground but it only seams to happen when under water. so far i have been able to reproduce it 100% of the time using (MFFS Projector Module Sphere, 10 MFFS Projector Module distance, MFFS Projector Upgrade NPC Defense, MFFS Projector Upgrade Sponge, MFFS Projector Upgrade Field Fusion, set to multitool switch, and field teleporter enabled) i have not tried to reproduce the crash with other settings as those are the ones my base is using. i would post the crash logs if it created them but due to the nature of it just indefinitely freeze the game and not actually crashing there are no logs generated and i am forced to use task manager to end javaw.exe
hope you are able to find whats causing it and can fix it. if you need more info just let me know.
best of luck and great mod btw - Paint
