I'm finally getting back into #uxn/#varvara, and have run into some trouble following the Compudanzas tutorial - I can build any given .tal file once, but after doing so once if I do so again I get

hello.tal line 0x0000: Memory overwrite: LIT.

in the terminal output from launcher.rom and the .tal file is corrupted - anyone have pointers on where to look to start debugging this? I don't have a lot of C skill at this point, so haven't dug much into the uxnasm source yet.

So |0100 moves the program location at that place, here's it's warning you that you're trying to write program data over itself.

Use like |0100 something |0200 something else |0300 something again

Also, you really should use BRK after a length of code, otherwise the program will start doing really weird stuff.

Also, while you're learning, don't use the launcher to assemble, the uxn assembler(uxnasm) has clearer error messages 😀 It'll be easier to follow along with the tutorial.
