I have an issue that I suspect is related to this mod. While playing I suddenly noticed that opening the menu (as in, the pop up menu where you can save and such) had become impossible. neither clicking the esc key nor the cogwheel symbol on screen worked. Weirdly enough, I had been able to open it earlier in the same game session. I realized that in the span of time between when the menu last opened, and opening it becoming impossible, I had in fact used the quay upgrade tool, which I had never used prior. I checked the output_log and noticed that every time I tried to open the menu, the following was printed once more in the log.
"UnifiedUI | [Info] 17,706.9841508 | QuayUpgradeTool (QuayUpgradeTool.QuayUpgradeTool) did not handle ESC key. Unified UI turns it off instead."
