As of Beta, for which I added some new data for part info summary strings, it's possible for those strings to be longer than the allotted area, and sometimes the game will crash when you are in INFO mode with such an item attached or in inventory.
Reported by Nikola Kolodziejczyk, and fixed for the next release, but for example it's currently possible for a crash to occur if you activate INFO ('Q') mode with something like an Omega Cannon attached.
(It's not guaranteed to crash, but it writes to random memory and can cause undefined behavior, which tends to eventually crash something :P)
Omega Cannon
Imp. Potential Cannon
Null Cannon
(...I think that's all of them, although the list could include a few more if you also have schematics for particular amazing high-tier weapons)
