Using Lootr 0.1.11.36 and Battle Tower Lite (Forge) on Forge 36.2.21,

The Golem's explosion will destroy the chest from Lootr according to testers of my modpack.

I haven't attempted to replicate it myself but I figure I should bring the issue up to you in case this was not intended

Unfortunately, this is an MCreator mod and quite difficult to understand.

From looking through the code, it uses the BREAK type of explosion, which implies that this functionality was desired. I'm hesitant to add an exclusion or blast resistance as this would render TNT somewhat useless.

An option is to make the normal chest blast resistant, but to leave the trapped chest susceptible to explosions. I'm not sure at this point what option would be best.

Thinking about this, that's not actually possible, as the "trap" in the desert pyramid is triggered by a pressure plate rather than by trapped chests. Thus, it would render that trap useless as well.

Personally, I would recommend looking into another type of Battle Towers mod, as I believe several exist for 1.16.5. This one seems badly designed, as it would break a normal loot container as well -- unless the original loot container was specifically blast proof?

I will definitely look into finding a different mod. Thank you for taking the time to looking issue and resolving it quickly.

No worries, sorry I couldn't be more help!
