Crash when toggling off removed envelope (any plugin) (FIXED)

[cfillion]

I'm getting this crash when toggling off envelopes I've just cleared/removed. I initially thought it happened only with Reaktor 5, but after more testing it crashed with ReaEQ as well.

This is with REAPER v5.33 on macOS 10.10:

It seems to be somewhat random. While here it crashes every time with Reaktor 5, with other plugins such as ReaEQ it either works fine, crashes like above, or freezes. Here's a spindump taken while REAPER was frozen: http://sprunge.us/TQcZ.

Thanks, fixing!
