4 years ago We've made a lot of fixes to lightsource code since this bug report was made, and I am currently unable to reproduce the bugs. Please make a new issue if you still encounter any lightsource bugs on devel-3.19.0!

(gdb) print *ls $3 = {next = 0x0, x = 0 '\000', y = 0 '\000', range = 1, flags = 2, type = 1, id = 0x0} Honestly I have no idea. There is also another issues here. impossible relink_light_sources: cant find m_id 991833 impossible maybe_write_ls: no id! [range=0] impossible save_light_sources: no id! [range=0] This can also an issue where lightsources end up off screen.

I dunno it crashes when you change levels and lightsources are the problem.
