• Crash Report Link: crash-2020-02-07_16.44.23-client.txt crash-2020-02-07_16.48.42-client.txt
• Affected Features: in-game guide (info calculator)
• Description: opening the transmitter tab on the info calculator crashes the game, but only when done from the sidebar of an other "related" tab.

sidenote: Volcano Block modpack, but AFAIK it shouldn't be related to the issue. Also it was marked as solved in 2016 (https://github.com/SonarSonic/Calculator/issues/151), but it seems like it is not.
