I build my own crypto coin using core 0.18 (source code from Litecoin) and got the following problem.

Everything is working fine I redid the whole process 5 times, but still have 1 problem whenever
I make a transaction it stays in 0/unconfirmed even after mining hundreds of blocks, in the memory pool.
(idk if this has something to do with it but I heard this problem could be because of lightspeed transactions.)

Thx, for helping 🙂
