Reload modules (F3 + M) debug shortcut doesn't work

[Zpiboo]

Bug Description

The expected log messages do show up. Though, after triggering the modules reload, module classes that are still unloaded fail to load afterward, resulting in a java.lang.NoClassDefFoundError.

Steps to Reproduce

1. Join a world with a module with classes that should load later
2. Press F3 + M before the said classes load
3. Notice how the log messages do show up, but nothing changes
4. Load the still unloaded classes
5. Observe that it causes a java.lang.NoClassDefFoundError

Expected Behavior

When pressing F3 + M, modules should have updated properly without causing class loading errors.
