[1.14.4] Forge Server Consistently Crashes #92

Closed Tsavoritel closed 4 years ago

Tsavoritel commented 4 years ago

Forge: 28.1.40 Mine+Slash: 2.8.18 Curios Forge: 1.0.0.3

Me and my friend are quite new to this however, we are able to get a vanilla server running fine, and a forge minecraft server running without the two mods needed to get it working. As soon as we launch it with the mods, it crashes only a second or two after the window pops up. We made the server from scratch numerous times, and the same thing happens over and over. in single player it seems to work fine, I've made it to level 15 without a single issue minus this. If you need me to post error logs I can probably supply them. Also sorry if the format is like, really off as this is my first issue to submit in GitHub

RobertSkalko commented 4 years ago

post FULL log files or i can only speculate what's wrong

Tsavoritel commented 4 years ago

lets see... i believe this is what you need? sorry for the late reply

// You should try our sister game, Minceraft!
