Hey there,
I'm currently working on a library that exposes some features of a game to lua scripts.
The issue that I'm facing somehow has to do with my custom luaj library. Whenever I call a function from my library (weirdly enough not my custom print though), luaj just stops executing all the following lines.
I already tried removing \ns from the input string, but that sadly did not solve anything.
Does anyone have an idea, what could be the problem here? LuaJ does not appear to throw any errors when it stops.

The library is assembled here: https://chonkyrabbit.eu/git/luaprocessors.git/tree/src/luaprocessors/lua/LuaExecutor.java#n151
The code gets executed here: https://chonkyrabbit.eu/git/luaprocessors.git/tree/src/luaprocessors/lua/LuaExecutor.java#n66

Just for completeness, here an example snippet:

print(mindustry.env.getTick())
mindustry.world.io.message.print("message1", mindustry.env.getTick()) # Not executed
print("test") # Not executed

Can anyone explain this?
Thanks!

Edit: I found a weird edge-case (which works)

v = mindustry.env.getTick()
mindustry.world.io.message.print("message1", v)
print(v)
