Issue #1. Bombs not leaving particle effects behind such as an explosion or smoke
Fix #1. Disable all addons and enable all Gredwitch' Addons, Next start a singleplayer game. After joining test the addon(s). Then re-enable all addons while in the singleplayer game still and then join back after all addons are enabled and should be fixed

Issue #2. Shell type not changing.
The shell type doesn't tell me if it's changing or not and/or the shell doesn't change. The type used to show on my screen then it went to the console and now it's completely gone, Please Help!

Possible Fix #2 Wait in-game for a few minutes and play around with the sweps/bombs/anything else that uses Gredwitch' base
